Now that the bootblock isn't added to cbfs anymore, on some targets it's
only conditionally build. One example would be Intel APL where it only
gets build when stitched into an IFWI. This is always done when
compiling for real targets but not by the CI builder. This adds a dummy
target to make sure the bootblock always gets buildtested.

Some platforms don't need a top aligned bootblock in cbfs like Intel
APL or modern AMD platforms as the bootblock is loaded differently.
So they don't need the top aligned cbfs bootblock.

The makefiles don't like cbfs file names with spaces in them so update
the file name with '_' instead of spaces. To keep the master header at
the top of cbfs, add a placeholder.
This removes the need to handle the cbfs master header in cbfstool.
This functionality will be dropped in a later CL.
On x86 reserve some space in the linker script to add the pointer.
On non-x86 generate a pointer inside a C struct file.
As a bonus this would actually fix the master header pointer mechanism
on Intel/APL as only the bootblock inside IFWI gets memory mapped.
TESTED on thinkpad X201: SeaBIOS correctly finds the cbfs master
header.

The printed address ranges in the tree (resource allocator and even

address to the real end address of the range). Though there is still
some code in the MTRR context which prints the ranges with an exclusive
end. This patch aligns the printing of ranges in the MTRR code to be
consistent among the tree so that the shown end addresses are now
inclusive.

"hb-mode" is a -machine flag for QEMU. "hb" stands for Hostboot, which

QEMU for PPC64 can run initial program in two different modes:
* hb-mode=off with load address 0x00000000
* hb-mode=on with load address 0x08000000
Real hardware always loads firmware at 0x08000000 and coreboot shouldn't
require a special build to be run on QEMU.
Memory layout is updated to reflect change of load address.

to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.
This patch was created by running

and doing some cursory review/cleanup on the result. Then doing the same

According to util/kbc1126/README.md, for these ECs to work, the
address and size of their two firmware should be written to $s-0x100`
(`$s` means the image size, done with kbc1126_ec_insert), which means
that every existing section (especially those used to store code)
should not overlap this address, otherwise the bootblock will get
damaged when inserting firmwares of the EC.
In this commit, ecfw_ptr is a structure initialized at build time
according to CONFIG_KBC1126_FW1_OFFSET and CONFIG_KBC1126_FW2_OFFSET
(to do so, they should be redefined as hex), and linked to
CONFIG_ECFW_PTR_ADDR within bootblock, so kbc1126_ec_insert is not
needed at build time any more.
