* Replace __bss_end__ with __bss_endSimon Glass2013-03-15-25/+25
| | | | | | | | | | | | | Note this is a tree-wide change affecting multiple architectures. At present we use __bss_start, but mostly __bss_end__. This seems inconsistent and in a number of places __bss_end is used instead. Change to use __bss_end for the BSS end symbol throughout U-Boot. This makes it possible to use the asm-generic/sections.h file on all archs. Signed-off-by: Simon Glass <sjg@chromium.org>
* mac: Fix the condition check for setting the MAC from the EEPROMHolger Hans Peter Freyther2013-02-20-2/+2
| | | | | | | | | | The issue got introduced in a cleanup by Manjunath Hadli in commit 826e99136e2bce61f3f6572e32d7aa724c116e6d. The eth_getenv_enetaddr_by_index method will validate the MAC addr and if none is set in the environment 0 will be returned. Set the MAC from the eeprom if no valid address is found in environment.

Moreover, make it a switch(), since the SSP ports are not mapped in such nice linear fashion on MX23, therefore having it a switch will simplify things there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add workaround for the following ARM errata: 743622 and 751472. The motivation for this change is the following kernel commit 62e4d357a (ARM: 7609/1: disable errata work-arounds which access secure registers), which removes the errata from multiplatform kernel. Since imx has been converted to multiplatform in the kernel, we need to apply such workarounds into the bootloader. Workaround code has been taken from arch/arm/mm/proc-v7.S from 3.7.1 kernel. Explanation of each erratum is provided at "Chip Errata for the i.MX 6Dual/6Quad" document available at: cache.freescale.com/files/32bit/doc/errata/IMX6DQCE.pdf Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
