2011-01-07	c5baa0e Browse files » Fix error handling with malloc, memalign etc. Introduce xmemalign(). ... The idea is to panic() when there is no memory available for normal operation. Exception: code which can consume arbitrary amount of RAM (example: files allocated in ramfs) must report error instead of panic(). This patch also fixes code which didn't check for NULL from malloc() etc. Usage: malloc(), memalign() return NULL when out of RAM. xmalloc(), xmemalign() always return non-NULL or panic().

	04191aa Browse files » cfi_flash: do not reset flash when probe fails ... The CFI flash driver starts at flash_init() which calls down into flash_get_size(). This starts by calling flash_detect_cfi(). If said function fails, flash_get_size() finishes by attempting to reset the flash. Unfortunately, it does this with an info->portwidth set to 0x10 which filters down into flash_make_cmd() and that happily smashes the stack by sticking info->portwidth bytes into a cfiword_t variable that lives on the stack. On a 64bit system you probably won't notice, but killing the last 8 bytes on a 32bit system usually leads to a corrupt return address. Which is what happens on a Blackfin system. based on U-Boot Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Jean-Christophe PLAGNIOL-VILLARD committed on 2 Dec 2010

2010-02-01	1e65863 Browse files » cfi_flash: fix alignment problem ... This patch fixes a alignment problem which may show during this scenario: - 32 or 64 attached NOR flash - flashing an image directly from network to the nor flash The involved network driver is "smc9111.c". The data that comes from the network stack and should be written into the flash isn't 32 bit alligned (at least with this network driver). This is probably due to the 48 bit wide ethernet addresses. However the "cfi_flash.c" driver doesn't handle this situation, and accesses the not-alligned address with a 32 bit pointer. This patch fixes the problem by reducing the access width if an alligment problem between source and destination is found.
