2012-08-07spi: Fix merge conflicts - MakefileMichal Simek
The patch "spi: tegra2: rename tegra2_spi.* to tegra_spi.*" (sha1: edffa63d3d6e76991998789f9fcbaa483731ca65) renamed tegra2_spi.c to tegra_spi.c and the patch "Merge branch 'master' of git://git.denx.de/u-boot-microblaze" (sha1: d978780b2e676c005460cd561f4f15b5220bdf49) has wrongly resolved confict. This patch fix it. Signed-off-by: Michal Simek <monstr@monstr.eu>
2012-08-07ext2fs: fix warning: 'blocknxt' may be used uninitialized with gcc 4.2Tom Rini
The above warning was introduced originally in 436da3c "ext2load: increase read speed" and fixed for newer toolchains in b803273 "ext2fs: fix warning: 'blocknxt' may be used uninitialized". This change did not fix the warning with gcc 4.2, as found in ELDK 4.2. If we rework the while loop to initalize blocknxt before entering the warning really goes away. Tested on am335x with an approx 7mb file and crc32 in U-Boot befor and after this change.

2012-08-06env_onenand: set ONENAND_MAX_ENV_SIZE to CONFIG_ENV_SIZEDavid du Colombier
This fix prevents env_import() CRC to fail when CONFIG_ENV_SIZE is not equal to 4096 bytes It also prevents mtd->read and mtd->write to be incomplete when the environment is larger than 4096 bytes. Signed-off-by: David du Colombier <0intro@gmail.com>
2012-07-31powerpc/82xx: adapt SDRAM settings for mgcoge3neGerlando Falauto
The HW guys suggested to change these two values. And these values are now identical to the values we use on mgcoge. PSDMR_WRC was set to 1C as it should lead to better performance.

2012-07-31powerpc/82xx: use SDRAM detection for mgcoge2neGerlando Falauto
mgcoge2ne was an intermediate step towards mgcoge3ne. One difference is the smaller SDRAM on mgcoge2ne (128MB). To support both boards with the same u-boot we use here the SDRAM detection. This patch enables SDRAM detection between 256MB and 128MB. So in addition to the existing 256MB geometry: 4 chips x 8M (13 rows, 10 cols) x 16 bit x 4 banks we can now also have 128MB geometry: 4 chips x 4M (13 rows, 9 cols) x 16 bit x 4 banks Signed-off-by: Gerlando Falauto <gerlando.falauto@keymile.com>
2012-07-31powerpc/82xx: add SDRAM detection for km82xxGerlando Falauto
This patch adds SDRAM detection feature to km82xx boards. To enable this feature, define CONFIG_SYS_SDRAM_LIST as the initializer for an array of struct sdram_conf_s. These structs will expose the bitfields within registers PSDMR and OR1 which have to be different between configurations; common bitfields will be defined, as usual, within CONFIG_SYS_PSDMR and CONFIG_SYS_OR1. If CONFIG_SYS_SDRAM_LIST is not defined, then the usual behavior is retained. Signed-off-by: Gerlando Falauto <gerlando.falauto@keymile.com>
2012-07-31powerpc/82xx: move km/km82xx-common.h within km82xx.hGerlando Falauto
The only file including km82xx-common.h is km82xx.h. So there is no need to have it as a separate file. Signed-off-by: Gerlando Falauto <gerlando.falauto@keymile.com>
2012-07-31powerpc/82xx: merge mgcoge.h and mgcoge3ne.h into km82xx.hGerlando Falauto
Since mgcoge and mgcoge3ne are the only km82xx boards, there is no need to keep them as separate .h config files. Therefore, make mgcoge3ne.h and mgcoge.h converge into a single km82xx.h file. Signed-off-by: Gerlando Falauto <gerlando.falauto@keymile.com>
