[PATCH 2/2] powerpc/8xx: Add microcode patch to move SMC parameter RAM.

2019-06-13 Thread Christophe Leroy
Some SCC functions like the QMC requires an extended parameter RAM. On modern 8xx (ie 866 and 885), SPI area can already be relocated, allowing the use of those functions on SCC2. But SCC3 and SCC4 parameter RAM collide with SMC1 and SMC2 parameter RAMs. This patch adds microcode to allow the relo
