image: fix IH_ARCH_... values for uImage compatibility
Commit 555f45d8f916 ("image: Convert the IH_... values to enums")
accidentally changed some IH_ARCH_... values.
Prior to that commit, there existed a gap between IH_ARCH_M68K and
IH_ARCH_MICROBLAZE, like follows.
#define IH_ARCH_SPARC64 11 /* Sparc 64 Bit */
#define IH_ARCH_M68K 12 /* M68K */
#define IH_ARCH_MICROBLAZE 14 /* MicroBlaze */
#define IH_ARCH_NIOS2 15 /* Nios-II */
The enum conversion broke the compatibility with existing uImage
files. Reverting 555f45d8f916 will cause build error unfortunately,
so here is a more easy fix.
I dug the git history and figured out the gap was introduced by
commit 1117cbf2adac ("nios: remove nios-32 arch"). So, I revived
IH_ARCH_NIOS just for filling the gap.
I added comments to each enum block. Once we assign a value to
IH_... it is not allowed to change it.
