powerpc: Explicitly include correct DT includes The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

powerpc: Make generic_calibrate_decr() the default ppc_md.calibrate_decr() is a mandatory item. Its nullity is never checked so it must be non null on all platforms. Most platforms define generic_calibrate_decr() as their ppc_md.calibrate_decr(). Have time_init() call generic_calibrate_decr() when ppc_md.calibrate_decr() is NULL, and remove default assignment from all machines.

powerpc: Move 32-bit probe() machine to later in the boot process This converts all the 32-bit platforms to use the expanded device-tree which is a pretty mechanical change. Unlike 64-bit, the 32-bit kernel didn't rely on platform initializations to setup the MMU since it sets it up entirely before probe_machine() so the move has comparatively less consequences though it's a bigger patch.

powerpc/512x: don't compile any platform DIU code if the DIU is not enabled If the DIU framebuffer driver is not enabled, then there's no point in compiling any platform DIU code, because it will never be used. Most of the platform code was protected in the appropriate #ifdef, but not all. This caused a break in some randconfig builds. This is only a problem on the 512x platforms. The P1022DS and MPC8610HPCD platforms are already correct. This patch reverts commit 12e36309f8774f4ccc769d5e3ff11ef092e524bc ("powerpc: Option FB_FSL_DIU is not really optional for mpc512x") and restores the ability to configure DIU support.

powerpc/5121: shared DIU framebuffer support MPC5121 DIU configuration/setup as initialized by the boot loader currently will get lost while booting Linux. As a result displaying the boot splash is not possible through the boot process. To prevent this we reserve configured DIU frame buffer address range while booting and preserve AOI descriptor and gamma table so that DIU continues displaying through the whole boot process. On first open from user space DIU frame buffer driver releases the reserved frame buffer area and continues to operate as usual.
