[memmap] Allow explicit colour selection for memory map debug messages2025-05-25T11:06:53+00:00Michael Brown2025-05-25T11:06:53+00:00urn:sha1:09140ab2c1a14b77d1e8beb407e500cb4deeb0ae
Provide DBGC_MEMMAP() as a replacement for memmap_dump(), allowing the
colour used to match other messages within the same message group.
Retain a dedicated colour for output from memmap_dump_all(), on the
basis that it is generally most useful to visually compare full memory
dumps against previous full memory dumps.

[memmap] Rename addr/last fields to min/max for clarity2025-05-23T15:55:42+00:00Michael Brown2025-05-23T15:55:42+00:00urn:sha1:036e43334ad94125dfe212480957fd397e51a053
Use the terminology "min" and "max" for addresses covered by a memory
region descriptor, since this is sufficiently intuitive to generally
not require further explanation.

[initrd] Split out initrd construction from bzimage.c2025-05-23T11:31:46+00:00Michael Brown2025-05-23T11:13:02+00:00urn:sha1:4a39b877dd165cc903da2e15cb1c42d1d115cc80
Provide a reusable function initrd_load_all() to load all initrds
(including any constructed CPIO headers) into a contiguous memory
region, and support functions to find the constructed total length and
permissible post-reshuffling load address range.

[initrd] Rename bzimage_align() to initrd_align()2025-05-22T15:28:15+00:00Michael Brown2025-05-22T12:41:21+00:00urn:sha1:029c7c4178d0122164770bf4a534aeb94d6c7698
Alignment of initrd lengths is applicable to all Linux kernels, not
just those in the x86 bzImage format.

[initrd] Move initrd reshuffling to be architecture-independent code2025-05-21T11:12:16+00:00Michael Brown2025-05-21T11:07:24+00:00urn:sha1:c1cd54ad74200a132aff5b3d0cfce8662dec5fe4
There is nothing x86-specific in initrd.c, and a variant of the
reshuffling logic will be required for executing bare-metal kernels on
RISC-V and AArch64.

[uaccess] Generalise librm's virt_offset mechanism for RISC-V2025-05-07T23:12:33+00:00Michael Brown2025-05-07T22:02:40+00:00urn:sha1:0279015d09f2653f5c47e8ad2d2dc180180271d1
The virtual offset memory model used for i386-pcbios and x86_64-pcbios
can be generalised to also cover riscv32-sbi and riscv64-sbi. In both
architectures, the 32-bit builds will use a circular map of the 32-bit
address space, and the 64-bit builds will use an identity map for the
relevant portion of the physical address space, with iPXE itself
placed in the negative (kernel) address space.
Generalise and document the virt_offset mechanism, and set it as the
default for both PCBIOS and SBI platforms.
