Eugeniy Paltsev 2f0d2f3ace ARC: adjust memblock_reserve of kernel memory ... commit a3010a0465 upstream. In setup_arch_memory we reserve the memory area wherein the kernel is located. Current implementation may reserve more memory than it actually required in case of CONFIG_LINUX_LINK_BASE is not equal to CONFIG_LINUX_RAM_BASE. This happens because we calculate start of the reserved region relatively to the CONFIG_LINUX_RAM_BASE and end of the region relatively to the CONFIG_LINUX_RAM_BASE. For example in case of HSDK board we wasted 256MiB of physical memory: ------------------->8------------------------------ Memory: 770416K/1048576K available (5496K kernel code, 240K rwdata, 1064K rodata, 2200K init, 275K bss, 278160K reserved, 0K cma-reserved) ------------------->8------------------------------ Fix that.
