Add the necessary DSDT files copied from tianocore to boot the RPi4.
In addition generate a board specific SSDT to dynamically enable/disable
ACPI devices based on FDT. This is required to support the various variants
and boot options. It also allows to test the code on QEMU 9.0 without
modifications, since it doesn't emulate PCIe yet.

Updates for RPi for 2024.10:
- board: rpi: remove leftover CONFIG_HW_WATCHDOG block
- arm: bcm283x: remove unused empty hw_watchdog_disable
- board: raspberrypi: Fix format specifier for printing rev_scheme
- Revert "arm: dts: bcm283x: Add minimal smbios information"
|
|
This was added in commit 45a6d231b2f (bcm2835_wdt: support for the
BCM2835/2836 watchdog), which did do 'select HW_WATCHDOG'. That
incarnation of the watchdog driver later got removed in
c7adc0b5f98 (watchdog: bcm2835_wdt: Remove unused BCM283x watchdog
driver and its references), but this block was left behind.
Another rpi watchdog driver has since been added, but that does not
select HW_WATCHDOG, so this remains dead and unused. Remove it.

When raspberrpi-4b platform boots up, there are 2 sets of same bootup
log displayed on HDMI monitor screen, it looks like the screen is split
into 2 parts. The root cause is that video format of u-boot is different
from kernel. The fixing "a8r8g8b8" video format is used in u-boot, but
"r5g6b5" video format from framebuffer node is used in kernel image. In
order to avoid weird display status on screen, it needs to set the correct
parameter for simple framebuffer node even if it has existed.

The RPI firmware adjusts several property values in the dtb it passes
to u-boot depending on the board/SoC revision. Inherit some of these
when u-boot loads a dtb itself. Specificaly copy:
* /model: The firmware provides a more specific string
* /memreserve: The firmware defines a reserved range, better keep it
* emmc2bus and pcie0 dma-ranges: The C0T revision of the bcm2711 Soc (as
present on rpi 400 and some rpi 4B boards) has different values for
these then the B0T revision. So these need to be adjusted to boot on
these boards
* blconfig: The firmware defines the memory area where the blconfig
stored. Copy those over so it can be enabled.
* /chosen/kaslr-seed: The firmware generates a kaslr seed, take advantage
of that.

OF_HOSTFILE is used on sandbox configs only. Although it's pretty
unique and not causing any confusions, we are better of having simpler
config options for the DTB.
So let's replace that with the existing OF_BOARD. U-Boot would then
have only three config options for the DTB origin.
- OF_SEPARATE, build separately from U-Boot
- OF_BOARD, board specific way of providing the DTB
- OF_EMBED embedded in the u-boot binary(should not be used in production

With the exceptions of ds109, ds414, icnova-a20-swac, nokia_rx51 and
stemmy, disable ATAG support. A large number of platforms had enabled
support but never supported a kernel so old as to require it. Further,
some platforms are old enough to support both, but are well supported by
devicetree booting, and have been for a number of years. This is
because some of the ATAGs related functions have been re-used to provide
the same kind of information, but for devicetree or just generally to
inform the user. When needed still, rename these functions to
get_board_revision() instead, to avoid conflicts. In other cases, these
functions were simply unused, so drop them.

When RPi4 is booted from USB Mass Storage, the firmware reports 947MiB of
the ARM memory (948 in case of the standard SD-card boot). This value is
not MMU_SECTION_SIZE aligned, so the dram_bank_mmu_setup() skips mapping
of the last 1MiB. This later causes u-boot in ARM 32bit mode to freeze,
because it relocated itself into that unmapped memory and fails to
execute.
Fix this by limiting the size of the first bank to the multiple of
MMU_SECTION_SIZE.

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:
It's a **mistake** to use typedef for structures and pointers.
Besides, using typedef for structures is annoying when you try to make
headers self-contained.
Let's say you have the following function declaration in a header:
void foo(bd_t *bd);
This is not self-contained since bd_t is not defined.
To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
#include <asm/u-boot.h>
void foo(bd_t *bd);
Then, the include direcective pulls in more bloat needlessly.
If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:
struct bd_info;
void foo(struct bd_info *bd);
Right, typedef'ing bd_t is a mistake.
I used coccinelle to generate this commit.
The semantic patch that makes this change is as follows:
<smpl>
@@
typedef bd_t;
@@
-bd_t
+struct bd_info

Virtually all callers of this function do the rounding on their own.
Some do it right, some don't. Instead of doing this in each caller,
do the rounding in efi_add_memory_map(). Change the size parameter
to bytes instead of pages and remove aligning and size calculation in
all callers.
There is no more need to make the original efi_add_memory_map() (which
takes pages as size) available outside the module. Thus rename it to
efi_add_memory_map_pg() and make it static to prevent further misuse
outside the module.

Up to now we only update the DRAM banks when we are define
CONFIG_BCM2711. But our one binary approach uses a config that supports
BCM2837 and BCM2711. As a result we only see one gibibyte of RAM on
Raspberry Pi 4, even if it has more RAM.

To update the dram bank information from device-tree we use
fdtdec_decode_ram_size() which expectes the the size-cells and
address-cells to be defined in the memory node. For normal system RAM
these values are defined in the root node. When the values differ from
the default values defined in the spec, we can end up with wrong RAM
bank information.
Switch to the "standard" way to update the RAM bank information to
avoid this.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.
