|/ | | | | | | | | | | | | The SUN_TOP_CTRL_FAMILY_ID register is at a fixed absolute address for all of our supported chips, so utilize its value to determine what the UARTA base address should be based on the value we read. Since the code is called both during decompressor when the MMU is off, and after the MMU has been turned on in the kernel, and we want to do the lookup only once, we use the same technique as tegra.S and have a shared storage location between the decompressor and the kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During my randconfig build testing, I found that a kernel with DEBUG_AT91_UART and ARCH_BCM_63XX fails to build: arch/arm/include/debug/at91.S:18:0: error: "CONFIG_DEBUG_UART_VIRT" redefined [-Werror] It turns out that the DEBUG_UART_BCM63XX option is enabled whenever the ARCH_BCM_63XX is, and that breaks multiplatform kernels because we then end up using the UART address from BCM63XX rather than the one we actually configured (if any). This changes the BCM63XX options to only have one Kconfig option, and only enable that if the user explicitly turns it on.

It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts. Linus Walleij also has some patchs to clean up the older ARM Realview platforms by finally introducing DT support, and Rob Herring has some for ARM Versatile which is now DT-only.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Footbridge has two debug ports that are handled a bit differently: The 8250 port uses the normal debug/8250.S implementation that is shared with a lot of other platforms, but it relies on the DEBUG_UART_8250 option to be turned on automatically instead of being selected by DEBUG_FOOTBRIDGE_COM1 as we do for most other platforms. I'm changing this to use a 'select' and change the dependency to the debug symbol rather than the platform symbol for consistency. The DC21285 UART has a separate top-level option, and relies on the traditional include/mach/debug-macro.S method. With the s3c64xx multiplatform series queued up for 4.5, it is now the last one that does this, so by moving this file to include/debug/dc21285.S, we can get all platforms to do things the same way.
