When switching back and forth between 32 to 64 bit mode, for example to
call a 32-bits FSP or to call the payload, new page tables in the
respective stage will be linked.
The advantages of this approach are:
- No need to determine a good place for page tables in CBFS that does
not overlap.
- Works with non memory mapped flash (however all coreboot targets
currently do support this)
- If later stages can use their own page tables which fits better with
the vboot RO/RW flow
A disadvantage is that it increases the stage size. This could be
improved upon by using 1G pages and generating the pages at runtime.
Note: qemu cannot have the page tables in the RO boot medium and needs
to relocate them at runtime. This is why keeping the existing code with
page tables in CBFS is done for now.
TEST: Booted to payload on google/vilbox and qemu/q35

This does the following:
- Top align the bootblock so that the only the memory needed gets used.
This might slightly reduce the time the PSP needs to decompress the
bootblock in memory
- Use a memory directive to assert that the 16bit code is inside the top
64K segment
- Use the program counter less. While the BDF linker is happy about
running the program counter backwards, LLD is not. There is no
downside to this.
- Use a symbol rather that the program counter for sections. LLD gets
confused when (.) is used along with '<': it places the section at the
start of the memory region, rather than at the program counter. Using
a variable name works around this.
- Use a 'last_byte' section to make sure the first instruction is at
0xfff0. Both the BDF and the LLD linkers seems to work well with this
code
TEST: Both BFD and LLD are able to link the bootblock

- drop leading underscore from _factory_initialize_tpm{1,2}() (external

- drop unused <security/vboot/tpm_common.h> include and sub-includes of

Testing on the unmatched shows the code no longer works completely
correctly; Linux has taken over the handling of misalignment
anyway, because handling it in firmware, with the growing
complexity of the ISA and the awkward way in which it
has to be handled, is more trouble than its worth.
Plus, we don't WANT misalignment handled, magically, in
firmware: the cost of getting it wrong is high (as I've
spent a month learning); the performance is terrible (350x
slowdown; and most toolchains now know to avoid unaligned
load/store on RISC-V anyway.
But, mostly, if alignment problems exist, *we need to know*,
and if they're handled invisibly in firmware, we don't.
The problem with invisible handling was shown a while back
in the Go toolchain: runtime had a small error, such that
many misaligned load/store were happening, and it was
not discovered for some time. Had a trap been directed
to kernel or user on misalignment, the problem would
have been known immediately, not after many months.
(The error, btw, was masking the address with 3,
not 7, to detect misalignment; an easy mistake!).
But, the coreboot code does not work any more any way,
and it's not worth fixing. Remove it.
Tested by booting Linux to runlevel 1; before,
it would hang on an alignment fault, as the
alignment code was failing (somewhere).
This takes the coreboot SBI code much closer to
revival.
