2013-03-15Replace __bss_end__ with __bss_endSimon Glass
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>
2013-02-20mac: Fix the condition check for setting the MAC from the EEPROMHolger Hans Peter Freyther

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.

2012-09-01DaVinci DA8xx: fix set_cpu_clk_info()Laurence Withers
For the DA8xx family of SoCs, the set_cpu_clk_info() function was not initialising the DSP frequency, leading to 'bdinfo' command output such as: [...snip...] ARM frequency = 300 MHz DSP frequency = -536870913 MHz DDR frequency = 300 MHz This commit provides a separate implementation of set_cpu_clk_info() for the DA8xx SoCs that initialises the DSP frequency to zero (since currently the DSP is not enabled by U-Boot on any DA8xx platform). The separate implementation is justified because there is no common code between DA8xx and the other SoC families. It is now much easier to understand the flow of the two separate functions.

2012-07-07DaVinci: fix ddr2 vtp i/o calibrationTroy Kisky
Previously, only the low 5 bits (NCH) were being transfered from DDRVTPR to DDRVTPIOCR, the bits 5-9 where zeroed. VTP_RECAL should be bit 15, not 18. The only mainline board affected by this change is davinci_sonata. The other Davinci boards define CONFIG_SKIP_LOWLEVEL_INIT. However, if the program that loads u-boot on these boards copied the code from u-boot, they will need fixed as well.

2012-02-27dm6467Tevm: Use a common configuration file for davinci_dm6467evm and ↵prabhakar.csengg@gmail.com
davinci_dm6467Tevm In commit 2d575e46859dd9127a9cec731ace77523e6ea2ab a separate header file was introduced for the DM6467T EVM, include/configs/davinci_dm6467Tevm.h. The substantial difference between the davinci_dm6467evm and the davinci_dm6467Tevm configuration is a single bit in the hardware revision that is passed to the Linux kernel and davinci_dm6467evm has REFCLK_FREQ = 27000000 where as davinci_dm6467Tevm.h has a REFCLK_FREQ = 33000000. This patch removes include/configs/davinci_dm6467Tevm.h. Instead the include/configs/davinci_dm6467evm.h configuration is used for DM6467T EVMs and renamed CFG_REFCLK_FREQ to CONFIG_REFCLK_FREQ and CONFIG_REFCLK_FREQ is defined in boards.cfg.
