2013-08-15ARM: AM33xx: Move s_init to a common placeHeiko Schocher
s_init has the same outline for all the AM33xx based board. So making it generic. This also helps in addition of new Soc with minimal changes.

2013-07-30am335x_evm: Add support to boot from NOR.Steve Kipisz
NOR requires that s_init be within the first 4KiB of the image so that we can perform the rest of the required pinmuxing to talk with the rest of NOR that we are found on. When NOR_BOOT is set we save our environment in NOR at 512KiB and a redundant copy at 768KiB. We avoid using SPL for this case and u-boot.bin is written directly to the start of NOR. We enclose the DMM-related parts of arch/arm/cpu/armv7/am33xx/emif4.c with TI81xx checks as at this time U-Boot does not discard unused sections in the main build and this code relies on functions specific to (and only provided in) ti81xx-related code.

2013-07-30am335x_evm: Add support for the NOR module on the memory capeSteve Kipisz
This patch adds support for the NOR module that attaches to the memory cape for a Beaglebone board.

2013-07-30am335x_evm: Rework board_is_foo() checksTom Rini
We rework the various board_is_foo() checks to take a pointer to struct am335x_baseboard_id rather than using a local copy in board.c. This allows us to make use of the same checks in mux.c as well as fixing problems when this code could be running from read-only memory.

2013-06-07am335x: enable falcon boot mode for mmc (raw and fat) and nandPeter Korsgaard
Jump into full u-boot mode if a 'c' character is received on the uart. We need to adjust the spl bss/malloc area to not overlap with the loadaddr of the kernel (sdram + 32k), so move it past u-boot instead. For raw mmc, we store the kernel parameter area in the free space after the MBR (if used). For nand, we use the last sector of the partition reserved for u-boot. This also enables the spl command in the full u-boot so the kernel parameter area snapshot can be created. Signed-off-by: Peter Korsgaard <peter.korsgaard@barco.com>
2013-06-05am33xx/omap: Move save_omap_boot_params to omap-common/boot-common.cTom Rini
We need to call the save_omap_boot_params function on am33xx/ti81xx and other newer TI SoCs, so move the function to boot-common. Only OMAP4+ has the omap_hw_init_context function so add ifdefs to not call it on am33xx/ti81xx. Call save_omap_boot_params from s_init on am33xx/ti81xx boards.

2012-11-02am335x: add initial AM335x IDK board supportMatthias Fuchs
This patch extends the am335x_evm board for the AM335x IDK. The IDK board uses MII for the ethernet phy (same as Beaglebone board) and MMC0 for storage (but without card detect line). The IDK uses UART3 for console. So u-boot must be build with CONFIG_SERIAL4 and CONFIG_CONS_INDEX=4 or for the am335x_evm_uart3 board configuration as introduced by Andrew Bradfords recent patch series "am33xx: Enable UART {1,2,3,4,5}...". When using the IDK with console on UART0, those patches are not required. In this case the board slightly needs to be modified. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd.eu>
