Guo Ren aefd9461d3 csky: Fixup cpu speculative execution to IO area ... For the memory size ( > 512MB, < 1GB), the MSA setting is: - SSEG0: PHY_START , PHY_START + 512MB - SSEG1: PHY_START + 512MB, PHY_START + 1GB But the real memory is no more than 1GB, there is a gap between the end size of memory and border of 1GB. CPU could speculatively execute to that gap and if the gap of the bus couldn't respond to the CPU request, then the crash will happen. Now make the setting with: - SSEG0: PHY_START , PHY_START + 512MB (no change) - SSEG1: Disabled (We use highmem to use the memory of 512MB~1GB) We also deprecated zhole_szie[] settings, it's only used by arm style CPUs. All memory gap should use Reserved setting of dts in csky system. Signed-off-by: Guo Ren <guoren@linux.alibaba.com>		2020-04-03 12:40:07 +08:00
