From af2536088e2feae2cf1274f48376e3310e0f709e Mon Sep 17 00:00:00 2001 From: Matthew McClintock Date: Fri, 18 May 2012 06:04:17 +0000 Subject: [PATCH] powerpc/p1022ds: add support for SPI and SD boot Add TLB mappings, board target options, and configuration items need for SPI/SD boot. Since P1022DS RevB board, the NOR flash have been changed to 16 bit/28bit address flash, therefore, when SDHC/ESPI booting and access to eLBC, the PMUXCR[0~1] must be set to 10b, and PMUXCR[9~10] must be set to 00b for them. Configure the PX_BRDCFG0[0~1] to 10b which is connected to SPI devices as SPI_CS(0:3)_B.
