XIP support in x86 was something of a mess. This patch does the following: - Generic ia32 SOC no longer defines a "flash" region as generic X86 devices don't have a microcontroller- like concept of flash. The same has been done for apollo_lake. - Generic ia32 and apollo_lake SOCs starts memory at 1MB. - Generic ia32 SOC may optionally have CONFIG_XIP enabled. The board definition must provide a flash region definition that gets exposed as DT_PHYS_LOAD_ADDR. - Fixed definitions for RAM/ROM source addresses in ia32's linker.ld when XIP is turned off. - Support for enabling XIP on apollo_lake SOC removed, there's no use-case. - acrn and gpmrb boards have flash and XIP related definitions removed. - qemu_x86 has a fake flash region added, immediately after system RAM, for use when XIP is enabled. This used to be in the ia32 SOC. However, the default for qemu_x86 is to now have XIP disabled. - Fixed tests/kernel/xip to run by default on boards that enable XIP by default, plus an additional test to exercise XIP on qemu_x86 (which supports it but has XIP switched off by default) The overall effect of this patch is to: - Remove XIP configuration for SOC/boards where it does not make any sense to have it - Support testing XIP on qemu_x86 via tests/kernel/xip, but leave it off by default for other tests, to ensure it doesn't bit-rot and that the system works in both scenarios. - XIP remains an available feature for boards that need it.
