From b6ae6765c5a9e5daa3799e4d65562d3184712506 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 9 Jun 2014 11:36:55 +0200 Subject: sunxi: Remove mmc DMA support The DMA code in sunxi_mmc.c is broken. mmc_trans_data_by_dma() allocates the dma descriptors on the stack, and then exits while the dma transfer is in progress, so the dma engine is reading stack memory which at that point may be re-used. So far we've gotten away with this by luck, but recent u-boot changes have shifted the stack start address by 16 bytes, which combined with dma alignment now exposes this problem. Since we end up just busy waiting for the dma engine anyway, this commit fixes things by simply removing the dma code, resulting in smaller bug-free code.

Just like the omap used on these boards, the sunxi SoCs do have a unique chip id, in the form of the 128 bit SID register: http://linux-sunxi.org/SID_Register_Guide So mimick the BeagleBoard-XM board code (commit 548a64d8) and use the chip id to generate a unique fixed MAC address. We check for the SID not being all 0, since some early A20 batches shipped without having there SID programmed. Note we use specific parts of the 128 bits, since some parts indicate the SoC family / revision, and thus are fixed. The algorithm for this was taken from the linux-sunxi.org kernels.

When declared inside a c file there is a static function, which might be inlined. Since SPL uses a define to declare the static inline it becomes part of the c file although it is declared in a header and clang will warn that you have introduced unused static functions. Add maybe_unused to prevent such warnings.

They are good helpers in both little and big endian cases. Port these two functions here from Linux:include/linux/kernel.h, cater the comment message to little/big endian cases.

The standard malloc() is pretty complicated: 1. It uses some BSS memory for its state, and BSS is not available before relocation 2. It supports algorithms for reducing memory fragmentation and improving performace of free(). Before relocation we could happily just not support free(). 3. It includes about 4KB of code (Thumb 2) and 1KB of data. However since this has been loaded anyway this is not really a problem. The simplest way to support pre-relocation malloc() is to reserve an area of memory and allocate it in increasing blocks as needed. This implementation does this. To enable it, you need to define the size of the malloc() pool as described in the README. It will be located above the pre-relocation stack on supported architectures. Note that this implementation is only useful on machines which have some memory available before dram_init() is called - this includes those that do no DRAM init (like tegra) and those that do it in SPL (quite a few boards). Enabling driver model preior to relocation for the rest of the boards is left for a later exercise.

Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away.

In this state U-Boot typically has a small amount of memory available. In adding support for driver model prior to relocation we must try to use as little memory as possible. In addition, on some machines the memory has not be inited and/or the CPU is not running at full speed or the data cache is off. These can reduce execution performance, so the less initialisation that is done before relocation the better. An immediately-obvious improvement is to only initialise drivers which are actually going to be used before relocation. On many boards the only such driver is a serial UART, so this provides a very large potential benefit. Allow drivers to mark themselves as 'pre-reloc' which means that they will be initialised prior to relocation. This can be done either with a driver flag or with a 'dm,pre-reloc' device tree property. To support this, the various dm scanning function now take a 'pre_reloc_only' parameter which indicates that only drivers marked pre-reloc should be bound.

Rather than try to guess when to switch to the real console, add a flag so we can be sure. This makes sure that sandbox can always output a panic() message, for example, and avoids silent failure (which is very annoying in sandbox).

While it may come to pass that we will move away from this numbering, the possibility seems remote at present. Given that devices within a uclass will have an implied numbering, it makes sense to build this into driver model as a core feature. The cost is fairly small in terms of code and data space. With each uclass having numbered devices we can ask for SPI port 0 or serial port 1 and receive a single device. Devices typically request a sequence number using aliases in the device tree. These are resolved when the device is probed, to deal with conflicts. Sequence numbers need not be sequential and holes are permitted. At present there is no support for sequence numbers using static platform data. It could easily be added to 'struct driver_info' if needed, but it seems better to add features as we find a use for them, and the use of -1 to mean 'no sequence' makes the default value somewhat painful.

Add functions to access a child in each of these ways. The index is typically used as a fallback when the sequence number is not available. For example we may use a serial UART with sequence number 0 as the console, but if no UART has sequence number 0, then we can fall back to just using the first UART (index 0). The device tree offset function is useful for buses, where they want to locate one of their children. The device tree can be scanned to find the offset of each child, and that offset can then find the device.

Example of buses include SPI and I2C. Typically +the bus provides some sort of transport or translation that makes it +possible to talk to the devices on the bus. + +Driver model provides a few useful features to help with implementing +buses. Firstly, a bus can request that its children store some 'parent +data' which can be used to keep track of child state. Secondly, the bus can +define methods which are called when a child is probed or removed. This is +similar to the methods the uclass driver provides. + +Here an explanation of how a bus fits with a uclass may be useful. Consider +a USB bus with several devices attached to it, each from a different (made +up) uclass: + + xhci_usb (UCLASS_USB) + eth (UCLASS_ETHERNET) + camera (UCLASS_CAMERA) + flash (UCLASS_FLASH_STORAGE) + +Each of the devices is connected to a different address on the USB bus. +The bus device wants to store this address and some other information such +as the bus speed for each device. + +To achieve this, the bus device can use dev->parent_priv in each of its +three children. This can be auto-allocated if the bus driver has a non-zero +value for per_child_auto_alloc_size. If not, then the bus device can +allocate the space itself before the child device is probed. + +Also the bus driver can define the child_pre_probe() and child_post_remove() +methods to allow it to do some processing before the child is activated or +after it is deactivated. + +Note that the information that controls this behaviour is in the bus's +driver, not the child's. In fact it is possible that child has no knowledge +that it is connected to a bus. The same child device may even be used on two +different bus types. As an example. the 'flash' device shown above may also +be connected on a SATA bus or standalone with no bus: + + xhci_usb (UCLASS_USB) + flash (UCLASS_FLASH_STORAGE) - parent data/methods defined by USB bus + + sata (UCLASS_SATA) + flash (UCLASS_FLASH_STORAGE) - parent data/methods defined by SATA bus + + flash (UCLASS_FLASH_STORAGE) - no parent data/methods (not on a bus) + +Above you can see that the driver for xhci_usb/sata controls the child's +bus methods. In the third example the device is not on a bus, and therefore +will not have these methods at all. Consider the case where the flash +device defines child methods. These would be used for *its* children, and +would be quite separate from the methods defined by the driver for the bus +that the flash device is connetced to. The act of attaching a device to a +parent device which is a bus, causes the device to start behaving like a +bus device, regardless of its own views on the matter. + +The uclass for the device can also contain data private to that uclass. +But note that each device on the bus may be a memeber of a different +uclass, and this data has nothing to do with the child data for each child +on the bus. + + Driver Lifecycle ---------------- diff --git a/drivers/core/device.c b/drivers/core/device.c index 42d250f4a48..166b0732ab9 100644 --- a/drivers/core/device.c +++ b/drivers/core/device.c @@ -291,6 +291,12 @@ int device_probe(struct udevice *dev) } dev->seq = seq; + if (dev->parent && dev->parent->driver->child_pre_probe) { + ret = dev->parent->driver->child_pre_probe(dev); + if (ret) + goto fail; + } + if (drv->ofdata_to_platdata && dev->of_offset >= 0) { ret = drv->ofdata_to_platdata(dev); if (ret) @@ -352,12 +358,20 @@ int device_remove(struct udevice *dev) goto err_remove; } + if (dev->parent && dev->parent->driver->child_post_remove) { + ret = dev->parent->driver->child_post_remove(dev); + if (ret) { + dm_warn("%s: Device '%s' failed child_post_remove()", + __func__, dev->name); + } + } + device_free(dev); dev->seq = -1; dev->flags &= ~DM_FLAG_ACTIVATED; - return 0; + return ret; err_remove: /* We can't put the children back */ diff --git a/include/dm/device.h b/include/dm/device.h index 20207ce61a0..c8a4072bcf7 100644 --- a/include/dm/device.h +++ b/include/dm/device.h @@ -118,6 +118,10 @@ struct udevice_id { * @remove: Called to remove a device, i.e. de-activate it * @unbind: Called to unbind a device from its driver * @ofdata_to_platdata: Called before probe to decode device tree data + * @child_pre_probe: Called before a child device is probed.

This patch adds opportunity to write Keystone U-boot image to NAND device using appropriate RBL ECC layout. This is needed only if RBL boots U-boot from NAND device and that's supposed that raw u-boot partition is used only for writing image. The main problem is that default Davinci ECC layout is different from Keystone RBL layout. To read U-boot image the RBL needs that image was written using RBL ECC layout. The BBT table is written using default Davinci layout and has to be updated using one. The BBT can be updated only while erasing chip or by forced bad block assigning, so erase function has to use native ecc layout in order to be able to write BBT correctly. So if we're writing to NAND U-boot address we use RBL layout for others we use default ECC layout. Also remove definition for CONFIG_CMD_NAND_ECCLAYOUT as there is no reasons to use ECC layout commands. It was added by mistake.

It requires to change names also in places where they're used. Align lines and remove redundant definitions in kardware-k2hk.h at the same time. Using common KS2_ prefix helps resolve redundant redefinitions and adds opportunity to use KS2_ definition across a project not thinking about what SoC should be used. It's more convenient and we don't need to worry about the SoC type in common files, hardware.h will think about that. The hardware.h decides definitions of what SoC to use.

But GPMC chip-select address-map can be configured in granularity of 16MB only. So this patch uses GPMC_SIZE_16M for all NAND devices. 2) NOR device are directly memory-mapped to CPU address-space, so its address-map size depends on actual addressable region in NOR FLASH device. So this patch uses CONFIG_SYS_FLASH_SIZE to derive GPMC chip-select address-map size configuration.
