* arm: Enable generic board supportSimon Glass2013-03-15-0/+15
| | | | | | | This enables generic board support so that ARM boards can define CONFIG_SYS_GENERIC_BOARD. Signed-off-by: Simon Glass <sjg@chromium.org>
* arm: Use sections header to obtain link symbolsSimon Glass2013-03-15-4/+1
| | | | | | | Include this header to get access to link symbols, which are otherwise removed. Signed-off-by: Simon Glass <sjg@chromium.org>
* Introduce generic link section.h symbol filesSimon Glass2013-03-15-0/+27
| | | | | | | | | | | | | | | | | | We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini <trini@ti.com> (version 5) Signed-off-by: Simon Glass <sjg@chromium.org>
* Replace __bss_end__ with __bss_endSimon Glass2013-03-15-29/+29
| | | | | | | | | | | | | 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.

| * tegra: add SPI SLINK driverAllen Martin2013-02-11-0/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add driver for tegra SPI "SLINK" style driver. This controller is similar to the tegra20 SPI "SFLASH" controller. The difference is that the SLINK controller is a genernal purpose SPI controller and the SFLASH controller is special purpose and can only talk to FLASH devices. In addition there are potentially many instances of an SLINK controller on tegra and only a single instance of SFLASH. Tegra20 is currently ths only version of tegra that instantiates an SFLASH controller. This driver supports basic PIO mode of operation and is configurable (CONFIG_OF_CONTROL) to be driven off devicetree bindings. Up to 4 devices per controller may be attached, although typically only a single chip select line is exposed from tegra per controller so in reality this is usually limited to 1. To enable this driver, use CONFIG_TEGRA_SLINK Signed-off-by: Allen Martin <amartin@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
