Move addresses for kernel, ramdisk and fdt blob to own variables. Add dtb blob loading to all existing boot scripts, dtb filenames were taken from vanilla kernel. Introduce new boot script bootcmd_legacy, which only loads a kernel and a ramdisk. Make this the default boot script. This should also restore the behaviour of the original bootloader.
How much memory do these platforms have? Having just spent a bunch of time issues about where to load what on TI platforms, I'm a little worried about some of the locations:
- "kernel_addr=0x00100000\0" \
Below 32MB which isn't optimal.
- "ramdisk_addr=0x00800000\0" \
- "fdt_addr=0x007f0000\0" \
This doesn't leave a whole lot of space for the kernel before overwriting either of these.
- "bootcmd_legacy=ide reset " \
"&& ext2load ide ${hdpart} ${kernel_addr} " \
Add CONFIG_CMD_FS_GENERIC and just 'load' here and elsewhere (incl fatload).
