When accessing register with multiple bit fields, the common approach is
to use clrsetbits_le32, for example:
clrsetbits(®, (1 << 0) | (0x3 << 1) | (0x7 << 10),
(1 << 0) | (0x1 << 1) | (0x5 << 10));
This hard to maintain because we have to calculate the mask values
manually, make sure the duplicated shift (offset) was set correctly.
And it may be even worse if the value to set will be based on some
runtime values (that many developers will do a if-block with two very
similar argument list), and leaving lots of magic numbers.
We want to encourage developers always giving field names, and have a
better way of setting fields. The proposed utility macros are:
DEFINE_BITFIELD(name, high_bit, low_bit)
EXTRACT_BITFIELD(value, name)
WRITE32_BITFIELDS(addr, name, value, [name2, value2, ...])
READ32_BITFIELD(addr, name)
Where a developer can easily convert from data sheet like
BITS NAME
26:24 SEC_VIO
Into a declaration
DEFINE_BITFIELD(SEC_VIO, 26, 24)
Then, a simple call can set the field as:
WRITE32_BITFIELDS(®, SEC_VIO, 2);
That is much easier to understand than
clrsetbits_le32(®, 0x7 << 24, 0x2 << 24);
And to extract the value:
READ32_BITFIELD(®, SEC_VIO)
That is equivalent to:
(read32(®) & 0x3) >> 24

With the support of various algorithms and banks in tlcl_extend(),
digest_algo parameter of tpm_extend_pcr() started defining the target
PCR bank in TPM2 case.
The OS expects coreboot to extend the SHA256 bank of BOOT_MODE_PCR.
The value that the OS expects coreboot to extend into BOOT_MODE_PCR
is the SHA1 digest of mode bits extended to the length of SHA256 digest
by appending zero bytes.
Thus the correct value for digest_algo passed into tpm_extend_pcr() for
BOOT_MODE_PCR is TPM_ALG_SHA256.
This didn't matter until adding the support for multiple digest introduced
by patches like https://review.coreboot.org/c/coreboot/+/33252, as
tlcl_extend always used SHA256 bank before.

GPI_GPE_STS updates are therefore masked, and we don't want to enable

get scared away, and developers only get angered and frustrated about
