[PATCH v8 1/7] RISC-V: Move DT mapping outof fixmap

From: Anup Patel Currently, RISC-V reserves 1MB of fixmap memory for device tree. However, it maps only single PMD (2MB) space for fixmap which leaves only < 1MB space left for other kernel features such as early ioremap which requires fixmap as well. The fixmap size can be increased by another 2
