The current ARM1176 CPU specific code is too specific to the SMDK6400 architecture. The following changes were necessary prerequisites for the addition of other SoCs based on ARM1176. Existing board's (SMDK6400) configuration has been modified to keep behavior unchanged despite these changes. 1. Peripheral port remap configurability The earlier code had hardcoded remap values specific to s3c64xx in start.S. This change makes the peripheral port remap addresses and sizes configurable. 2. U-Boot code relocation support Most architectures allow u-boot code to run initially at a different address (possibly in NOR) and then get relocated to its final resting place in RAM. Added support for this capability in ARM1176 architecture. 3. Disable TCM if necessary If a ROM based bootloader happened to have initialized TCM, we disable it here to keep things sane. 4. Remove unnecessary SoC specific includes ARM1176 code does not really need this SoC specific include. The presence of this include prevents builds on other ARM1176 archs. 5. Modified virt-to-phys conversion during MMU disable The original MMU disable code masks out too many bits from the load address when it tries to figure out the physical address of the jump target label. Consequently, it ends up branching to the wrong address after disabling the MMU. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
