This commit sets two additional variables in the default BOOTCOMMAND.
Adding 'boot=mmc' and 'addr_fit=0x8b000000' removes the need for a
special 'uEnv.txt' to be created. The 'addr_fit' variable is the key
piece here. It is normally defined as 0x90000000, in the macro
DEFAULT_FIT_TI_ARGS. For this OMAP34XX board, 0x8b000000 works without
touching other varibles. This was tested with a 'fitImage' created
using the following FIT source:
----------------------------------------------------------------------
/dts-v1/;
/ {
description = "Simple image with single Linux kernel and FDT blob";
#address-cells = <1>;
images {
kernel {
description = "Linux kernel: omap2plus";
data = /incbin/("./zImage");
type = "kernel";
arch = "arm";
os = "linux";
compression = "none";
load = <0x80008000>;
entry = <0x80008000>;
hash-1 {
algo = "sha256";
};
};
fdt-omap3-evm.dtb {
description = "FDT: omap3-evm.dtb";
data = /incbin/("./omap3-evm.dtb");
type = "flat_dt";
arch = "arm";
compression = "none";
load = <0x8ff00000>;
hash-1 {
algo = "sha256";
};
};
};
configurations {
default = "conf-omap3-evm.dtb";
conf-omap3-evm.dtb {
description = "Boot Linux kernel with FDT blob";
kernel = "kernel";
fdt = "fdt-omap3-evm.dtb";
};
};
};
----------------------------------------------------------------------
Additionally, the default environment is now stored in "uboot.env" on
the FAT partition of MMC '0'.
