with this patch, this mpc8313 board does this:
U-Boot 2009.06-00524-g28958b8 (Jul 23 2009 - 18:33:11) MPC83XX
Reset Status:
CPU: e300c3, MPC8313E, Rev: 1.0 at 333.333 MHz, CSB: 166.667 MHz Board: Freescale MPC8313ERDB I2C: ready DRAM: 128 MB FLASH: ## Unknown FLASH on Bank 1 - Size = 0x00000000 = 0 MB *** failed *** ### ERROR ### Please RESET the board ###
and when reverted, it boots normally, so the board wants to
agree that
this patch is reverted.
Flash is mapped cacheable on 8313erdb (and some other 83xx boards) -- it shares a BAT with the locked cache area.
Yes. Scott is right. The rootcause is the classic PPC has not enough BAT.
