[U-Boot] [PATCH 1/2] cmd_bootm.c: Make bootz consume 'bootz' from argv, decrement argc

Like 'bootm', 'bootz' needs to consume 'bootz' so that the rest of the state functions will work.

As a zImage does not have a U-Boot header, we cannot really do what BOOTM_STATE_FINDOTHER does, exactly. Break the ramdisk/fdt portions of bootm_find_other into bootm_find_ramdisk/fdt which can be called in both cases.

I found that the Raspberry Pi was randomly crashing with recent u-boot/master (bisect points at/near commit 35fc84f "Refactor the bootm command to reduce code duplication"; there is some slight variation in symptoms around there), or sometimes just spewing errors from bootz. I found the following commits on the mailing list:
e1ec5e0 cmd_bootm.c: Make bootz handle BOOTM_STATE_FINDOTHER itself c83a89d cmd_bootm.c: Make bootz consume 'bootz' from argv, decrement argc d18cab6 bootm: Add the missing PREP stage to bootz and correct image handling 4766b32 bootm: Clean up bootz_setup() function f65d734 bootm: Require boot function only if it is about to be used bf6f341 bootm: Disable interrupts only when loading a01d5e4 bootm: Handle errors consistently
... and the combination of all 7 of them (but not just Simon's 5 patches) seems to solve this, so,

Thanks Stephen. Is this with an attached dtb or not? What 'bootz' command line are you testing here? I just want to make sure we are covering all the options

This is a separate kernel and DTB; the command-line is roughly:
bootz addr_of_zimage - addr_of_dtb

This and 2/2 have now been applied to u-boot/master.
