* env_nand: return error when no device is foundMike Frysinger2010-08-13-0/+2
| | | | | | | | | | | | | Currently, if there is an error probing the NAND chip and the env is based in NAND, the readenv() function will use a NULL function pointer and thus jump to address 0. Here I just check for a non-zero value of blocksize as that shouldn't be zero when a valid device is found, but perhaps there is a better way for someone familiar with the NAND internals to suggest.

* NAND: environment offset in OOB (CONFIG_ENV_OFFSET_OOB)Ben Gardiner2010-07-12-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a re-submission of the patch by Harald Welte <laforge@openmoko.org> with minor modifications for rebase and changes as suggested by Scott Wood <scottwood@freescale.com> [1] [2]. This patch enables the environment partition to have a run-time dynamic location (offset) in the NAND flash. The reason for this is simply that all NAND flashes have factory-default bad blocks, and a fixed compile time offset would mean that sometimes the environment partition would live inside factory bad blocks. Since the number of factory default blocks can be quite high (easily 1.3MBytes in current standard components), it is not economic to keep that many spare blocks inside the environment partition. With this patch and CONFIG_ENV_OFFSET_OOB enabled, the location of the environment partition is stored in the out-of-band (OOB) data of the first block in flash. Since the first block is where most systems boot from, the vendors guarantee that the first block is not a factory default block. This patch introduces the 'nand env.oob' command, which can be called from the u-boot command line. 'nand env.oob get' reads the address of the environment partition from the OOB data, 'nand env.oob set {offset,partition-name}' allows the setting of the marker by specifying a numeric offset or a partition name.

* shannon/INFERNO: fix special handling of environment configurationWolfgang Denk2010-07-04-4/+0
| | | | | | | | | | | Remove some INFERNO related #ifdef's from common environment code by fixing the board configuration settings (add CONFIG_ENV_SECT_SIZE). While we are at it, fix comment which incorrectly talks about 4 KB environment size, while it's actually 0x4000 = 16 KiB. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Rolf Offermanns <rof@sysgo.de>
* env_nand.c: print error message and fail gracefullyWolfgang Denk2010-01-27-0/+7
| | | | | | | | | env_nand.c would crash silently if a malloc() for the environment buffers failed; make it print an error message and fail gracefully, i. e. use the default environment then. Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-by: John Rigby <jcrigby@gmail.com>
* env: kill off default_environment_sizeMike Frysinger2009-08-09-1/+0
| | | | | | | | | The only environment type that uses this variable is spi flash, and that is only because it is reimplementing the common set_default_env() function. So fix the spi flash code and kill off the default_environment_size in the process. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Remove legacy NAND and disk on chip code.Scott Wood2009-07-16-4/+0
| | | | | | | | | | | | | Legacy NAND had been scheduled for removal. Any boards that use this were already not building in the previous release due to an #error. The disk on chip code in common/cmd_doc.c relies on legacy NAND, and it has also been removed. There is newer disk on chip code in drivers/mtd/nand; someone with access to hardware and sufficient time and motivation can try to get that working, but for now disk on chip is not supported.

* nand_spl: read environment early, when booting from NAND using nand_splGuennadi Liakhovetski2009-07-07-13/+30
| | | | | | | | | | | | Currently, when booting from NAND using nand_spl, in the beginning the default environment is used until later in boot process the dynamic environment is read out. This way environment variables that must be interpreted early, like the baudrate or "silent", cannot be modified dynamically and remain at their default values. Fix this problem by reading out main and redundand (if used) copies of the environment in the nand_spl code.
