* mxs: Convert sys_proto.h prefixes to 'mxs'Otavio Salvador2012-09-01-3/+3
| | | | | | | The sys_proto.h functions (except the boot modes) are compatible with i.MX233 and i.MX28 so we use 'mxs' prefix for its methods. Signed-off-by: Otavio Salvador <otavio@ossystems.com.br>
* arm: omap: Fix switching back to nandecc sw.Jeroen Hofstee2012-09-01-0/+1
| | | | | | | | | | | | | | | | | | | | | | Orjan Friberg wrote at [1]: "For the beagleboard, ecc.size is not explicitly set when doing 'nandecc sw'. If it's not set for the NAND_ECC_SOFT case in nand_scan_tail, it's set to 256 bytes. When doing 'nandecc hw', ecc.size is set to 512 bytes. Hence, when changing back to 'nandecc sw' ecc.size remains at 512 bytes and suddenly the format has changed." No patch has been submitted and the issue was still present. This patch adds the mentioned solution. Tested on a tam3517 board.

| | | | | | | | | | | | | | | | | | | | | | Commit a4ed3b6 "sf: inline data constants" modified winbond.c's page_size from 256 to 4096. This prevents either/both of "sf write" writing the correct data, or "sf read" from reading the correct data back. This allows U-Boot running on Compulab Tegra to upgrade itself.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are more than the M25Pxx serial flashs that can be used with the stmicro driver, for example: the M25PXxx or N25Qxx serie. All these chips have burned in the original stmicro manufacture id 0x20 together with a standard two-byte signature.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 54652991 Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips fixes a problem for Numonyx P33/P30 flashes for 256-Mbit, but this leads to problems for smaller versions of this chip e.g. the 32Mbit version with deviceid 0x16 on mgcoge. So move the code for this work around to an own function and check previously manufacturer id and device id to not break other flashes which don't need this work around.

The idea is to allow each and every device using the APBH DMA block to configure and request only the channels it uses, instead of making it call init for all the channels as is now. The common DMA block init part, which only configures the block, is then called from CPUs arch_cpu_init() call.
