This patchset adds support for loading a XLR/XLP kernel compiled with a CKSEG2 load address. The changes are to: - move the existing MAPPED_KERNEL option from sgi-ip27 to common config - Add a plat_mem_fixup function to arch_mem_init which will allow the platform to calculate the kernel wired TLB entries and save them so that all the CPUs can set them up at boot. - Update PAGE_OFFSET, MAP_BASE and MODULE_START when mapped kernel is enabled. - Update compressed kernel code to generate the final executable in KSEG0 and map the load address of the embedded kernel before loading it. - Use wired entries of sizes 256M/1G/4G to map the available memory on XLP9xx and XLP2xx Comments and suggestions welcome.
