[U-Boot] omap_gpmc: Do not default to HAM1 when SW ECC is selected
by Adam YH Lee 06 Mar '15

06 Mar '15

The ECC scheme selection algorithm in OMAP GPMC appears to be left untested when BCH8 handling code was added. Running 'nandecc sw' defaults to HAM1 even if the board is using another scheme (ex. OMAP_ECC_BCH8_CODE_HW_DETECTION_SW on OMAP3). This results in unrecoverable ECC errors when reading data. This commit fixes the behavior by checking for CONFIG_BCH and using the scheme defined by CONFIG_NAND_OMAP_ECCSCHEME in the board configuration file. This has been tested on Gumstix Overo (OMAP3).

[U-Boot] [PATCH v2] mtd: nand: omap_gpmc: Make ready/busy pins configurable
by sojkam1＠fel.cvut.cz 06 Mar '15

06 Mar '15

From: Michal Sojka <sojka(a)merica.cz> Commit fb384c4720ca7496775d6578f184bf628db73456 introduced the use of WAIT0 pin for determining whether the NAND is ready or not. This only works if all NAND chips are connected to WAIT0. If some chips are connected to the other available pin WAIT1, nand_wait() does not really wait and prints a WARN_ON message. This patch allows the board to provide configuration of which chip is connected to which WAITx signal. For example, one can define in include/configs/foo.h: #define CONFIG_NAND_OMAP_GPMC_WSCFG 0,0,1,1 This would mean that chips using to CS0 and 1 are connected to WAIT0 and chips with CS2 and 3 are connected to WAIT1.
