mtd: nand: omap_gpmc: Always use ready/busy pin

2014-12-05T02:28:31Z

The functions to detect the state of the ready / busy signal is already available but only used in the SPL case. Lets use it always, also for the main U-Boot. As all boards should have this HW connection. Testing on Siemens Draco (am335x) showed a small perfomance gain by using this ready pin to detect the NAND chip state. Here the values tested on Draco with Hynix 4GBit NAND: Without NAND ready pin: U-Boot# time nand read 80400000 0 400000 NAND read: device 0 offset 0x0, size 0x400000 4194304 bytes read: OK time: 2.947 seconds, 2947 ticks With NAND ready pin: U-Boot# time nand read 80400000 0 400000 NAND read: device 0 offset 0x0, size 0x400000 4194304 bytes read: OK time: 2.795 seconds, 2795 ticks So an increase of approx. 5%.

mtd: nand: s3c: Unify the register definition and naming

2014-11-27T05:21:43Z

Merge struct s3c2410_nand and struct s3c2440_nand into one unified struct s3c24x0_nand. While at it, fix up and rename the functions to retrieve the NAND base address and fix up the s3c NAND driver to reflect this change.

mtd/nand/vf610_nfc: Disable subpage writes

2014-11-27T01:53:49Z

This patch disables subpage writes for vf610_nfc nand driver. This is required, as without this fix, writing unaligned u-boot images with DFU results in a hang. Trying to write unalgined binary images also results in a hang, without disabling subpage writes. Patch has been tested on a Colibri VF61 module. Signed-off-by: Sanchayan Maity

mtd: denali: set some registers after nand_scan_ident()

2014-11-27T01:53:22Z

Some but not all of implementations of the Denali NAND controller have hardware circuits to detect the device parameters such as page_size, erase_size, etc. Even on those SoCs with such hardware supported, the hardware is known to detect wrong parameters for some nasty (almost buggy) NAND devices. The device parameters detected during nand_scan_ident() are more trustworthy. This commit sets some hardware registers to mtd->pagesize, mtd->oobsize, etc. in the code between nand_scan_ident() and nand_scan_tail().

mtd: denali: use CONFIG_SYS_NAND_SELF_INIT

2014-11-27T01:53:19Z

Some variants of the Denali NAND controller need some registers set up based on the device information that has been detected during nand_scan_ident(). CONFIG_SYS_NAND_SELF_INIT has to be defined to insert code between nand_scan_ident() and nand_scan_tail(). It is also helpful to reduce the difference between this driver and its Linux counterpart because this driver was ported from Linux. Moreover, doc/README.nand recommends to use CONFIG_SYS_NAND_SELF_INIT. Signed-off-by: Masahiro Yamada Cc: Scott Wood Cc: Chin Liang See

nand: reinstate lazy bad block scanning

linux/kernel.h: sync min, max, min3, max3 macros with Linux

2014-11-23T11:48:30Z

U-Boot has never cared about the type when we get max/min of two values, but Linux Kernel does. This commit gets min, max, min3, max3 macros synced with the kernel introducing type checks. Many of references of those macros must be fixed to suppress warnings. We have two options: - Use min, max, min3, max3 only when the arguments have the same type (or add casts to the arguments) - Use min_t/max_t instead with the appropriate type for the first argument Signed-off-by: Masahiro Yamada Acked-by: Pavel Machek Acked-by: Lukasz Majewski Tested-by: Lukasz Majewski [trini: Fixup arch/blackfin/lib/string.c] Signed-off-by: Tom Rini

dm: spi: Use device_bind_driver() instead of our own function

2014-11-22T09:16:48Z

The SPI function does the same thing, so we may as well just use the new generic function. The 'cs' parameter was not actually used, so can be dropped. Signed-off-by: Simon Glass Reviewed-by: Jagannadha Sutradharudu Teki Acked-by: Heiko Schocher
