--snip--
Do we really need all these directories? No chance to use common code at least for some of them?
Provided we assume that the ARM Unified Assembler Language will eventually be supported in the mainline gcc code, we could manage with new directories:
./lib_armv6 ./cpu/armv6 ./cpu/armv7 ./include/asm-arm/arch-v6 ./include/asm-arm/arch-v7
,using ifdefs until the UAL support arrives.
The only code in these directories would be any assembler code required.
Currently arm directories hold about 150K assember code (.S) files Some of this code is common. Were this to be removed I believe the v6/v7/thumb support could be added without overall increase in the U-Boot source size.
