* ARM: IGEP0033: Add support to boot from NAND.Enric Balletbo i Serra2013-08-15-5/+27
| | | | | | | | | | | | | | | | | Add to the default environment the possibily to boot from NAND using a ubi rootfs. Also the partition scheme is set as follows: Start Size SPL : 0x00000000 0x00080000 (512KiB) U-Boot : 0x00080000 0x00100000 (1MiB) U-Boot Env : 0x00180000 0x00020000 (128KiB) File System : 0x001C0000 - The ubiboot script gets the kernel and the dtb file from the boot directory of the File System.

* ARM: IGEP0033: Add support for Flattened Device Tree.Enric Balletbò i Serra2013-08-15-20/+13
| | | | | | | | | | | Now, the default kernel to boot the IGEP COM AQUILA is device tree based. As old kernel is deprecated we should adapt the boot commands to use DTB files. Also, with v3.9 and later of the Linux Kernel, uImage isn't builtable anymore by default, so we should switch to use the bootz command.

| | | | | | | | | Some boards, such as the BeagleBone Black, have an eMMC chip intstead of NAND. We can use the eMMC boot partition to store the environment, since it isn't used for anything else.

* am335x_evm: Add support to boot from NOR.Steve Kipisz2013-07-30-11/+182
| | | | | | | | | | | | | | | | | | 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.

* omap3_beagle: support booting from zImage and device tree as last optionNishanth Menon2013-07-26-0/+8
| | | | | | | | | | | | | | If no other bootoption works, try loading up device tree and zImage. This is selected as the last option to allow backward compatibility as well as support the recent trend in moving kernel boot to using zImage and device tree. NOTE: if uImage is present in bootpart, it will try this first and will assume this is to be booted with bootm (so may be concatenated image or plain vanilla ATAG MACHINE_ID based image) Signed-off-by: Nishanth Menon <nm@ti.com>
