Work in progress: - began to integrate the SMP/CPU stuff from the old boot loader; currently disabled, though - began VESA/VGA support - added temporary boot splash screen; it's a bit of a hack and only seem to work in Bochs 2.0.2 for now... (but hey, it looks good ;-)) git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8016 a95241bf-73f2-0310-859d-f6bbb57e9c96

/*
SMP integration work. Separated initialization from booting the other CPUs; this way, it won't mess with the MMU anymore after mmu_init_for_kernel() has been called. No other real changes; still disabled, still doesn't work (on my machine at least). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12284 a95241bf-73f2-0310-859d-f6bbb57e9c96

cpu: Extract shared x86 code from efi & bios_ia32 This issue was initially detected by PVS Studio (issue number V547) and fixed as part of Google Code-in 2019. The initial problem was the calculate_cpu_conversion_factor function which had been copied in the BIOS and EFI versions of the boot code. Further investigation led to more duplicated or very similar functions being identified. Introduce an arch_cpu.h for the x86 boot platform to group these things in a single place, and adjust the BIOS and EFI code to call into that. Note that the BIOS and EFI code is still a little platform specific, ideally there should be a boot_arch_cpu_init() function for each architecture as already done for openfirmware and u-boot. Also remove some irrelevant comments from copypasted files for other architectures, as that was filling my git grep with useless noise.
