Merge patch series "remove size limit on XIP kernel"

Nam Cao <namcao@linutronix.de> says: Hi, For XIP kernel, the writable data section is always at offset specified in XIP_OFFSET, which is hard-coded to 32MB. Unfortunately, this means the read-only section (placed before the writable section) is restricted in size. This causes build failure if the kernel gets too large. This series remove the use of XIP_OFFSET one by one, then remove this macro entirely at the end, with the goal of lifting this size restriction. Also some cleanup and documentation along the way. * b4-shazam-merge riscv: remove limit on the size of read-only section for XIP kernel riscv: drop the use of XIP_OFFSET in create_kernel_page_table() riscv: drop the use of XIP_OFFSET in kernel_mapping_va_to_pa() riscv: drop the use of XIP_OFFSET in XIP_FIXUP_FLASH_OFFSET riscv: drop the use of XIP_OFFSET in XIP_FIXUP_OFFSET riscv: replace misleading va_kernel_pa_offset on XIP kernel riscv: don't export va_kernel_pa_offset in vmcoreinfo for XIP kernel riscv: cleanup XIP_FIXUP macro riscv: change XIP's kernel_map.size to be size of the entire kernel ...
