| | | | | | | | | | | | | | | | | | | | | | 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. In preperation to support all these chips the stmicro driver have to decode the full 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.

* sf: unify erase commandsMike Frysinger2012-03-04-71/+18
| | | | | | | | Analysis of the flash drivers shows that they all use 0x20 if the erase size is 4KiB, or 0xd8 if it's larger. So with this info in hand, we can unify all the erase functionality in one place. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sf: inline data constantsMike Frysinger2012-03-04-105/+12

However, it was specific to spear platforms. This commit converts the same driver to a more generic driver.

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.
