-Subject: [PATCH 4/6] MIPS: bootm: rework and fix broken bootm code
-Organization: O.S. Systems Software LTDA.
-
-The move to 'generic board' as well as changes in the generic
-bootm code broke the boot of FIT uImage's. Especially uImage's
-with additional initramfs images or FDT's do not work anymore.
-
-Refactor the bootm code to work again with the generic bootm code.
-
-Always relocate ramdisk and FDT in step 'bootm prep' because the
-generic bootm code does this only for legacy uImage's.
-
-Move the step 'bootm cmdline' to 'bootm prep' because the Linux
-kernel parameters rd_start and rd_size have to be initialized after
-the relocation of the ramdisk.
-
-Furthermore support the step 'bootm fake'.
-
-Upstream-Status: Backport [2016.01]
