Subject: [MIPS] TXx9: Cleanups for 64-bit support
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=255033a9bb900a06c9a7798908ce12557d24fb66;p=openwrt%2Fstaging%2Fblogic.git

[MIPS] TXx9: Cleanups for 64-bit support

* Unify (and fix) mem_tx4938.c and mem_tx4927.c
* Simplify prom_init
* Kill volatiles and unused definitions for tx4927.h and tx4938.h
