[U-Boot-Users] [PATCH][MIPS] Use jr as register jump instruction

[Shinya Kuribayashi <skuribay@ruby.dti.ne.jp>]

Current assembler codes are inconsistent in the way of register jump
instruction usage; some use jr, some use j. Of course GNU as allows both
usages, but as can be expected from `Jump Register' the mnemonic `jr' is
more intuitive than `j'. For example, Linux doesn't have `j <reg>' usage
at all.
