2013-02-28sandbox: Add un/map_sysmen() to deal with sandbox's ram_bufSimon Glass
Sandbox doesn't actually provide U-Boot access to the machine's physical memory. Instead it provides a RAM buffer of configurable size, and all memory accesses are within that buffer. Sandbox memory starts at 0 and is CONFIG_DRAM_SIZE bytes in size. Allowing access outside this buffer might produce unpredictable results in the event of an error, and would expose the host machine's memory architecture to the sandbox U-Boot. Most U-Boot functions assume that they can just access memory at given address. For sandbox this is not true. Add a map_sysmem() call which converts a U-Boot address to a system address. In most cases this is a NOP, but for sandbox it returns a pointer to that memory inside the RAM buffer. To get a U-Boot feature to work correctly within sandbox, you should call map_sysmem() to get a pointer to the address, and then use that address for any U-Boot memory accesses.

2013-02-28sandbox: Improve sandbox serial port keyboard interfaceTaylor Hutt
Implements the tstc() interface for the serial driver. Multiplexing the console between the serial port and a keyboard uses a polling method of checking if characters are available; this means that the serial console must be non-blocking when attempting to read characters.

2013-02-20mac: Fix the condition check for setting the MAC from the EEPROMHolger Hans Peter Freyther
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.

2013-02-19malloc: make malloc_bin_reloc staticGabor Juhos
On architectures where manual relocation is needed, the 'malloc_bin_reloc' function must be called after 'mem_malloc_init'. Make the 'malloc_bin_reloc' function static and call it directly from 'mem_malloc_init' instead of calling that from board_init_{r,f} functions of the affected architectures.

2013-02-12MIPS: add dynamic relocation supportGabor Juhos
The code handles relocation entries with the following relocation types only: mips32: R_MIPS_REL32 mips64: R_MIPS_REL+R_MIPS_64 xburst: R_MIPS_REL32 Other relocation entries are skipped without processing. The code must be extended if other relocation types must be supported. Add -pie to LDFLAGS_FINAL to generate the .rel.dyn fixup table, which will be applied to the relocated image before transferring control to it. The CONFIG_NEEDS_MANUAL_RELOC is not needed after the patch, so remove that as well. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

2013-02-11tegra: add SPI SLINK driverAllen Martin
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>
