Fixed GUID of CapsuleUpdate* variables and an issue with coalesced capsule overwriting cbmem.

Same story as https://github.com/Dasharo/coreboot/pull/527, but since this has better branch name, perhaps closing #527 and using this as a target would make more sense. In any case, there are comments that hasn't been marked as resolved (@miczyg1 ping), I won't close the other PR until then to not mess up with how GH shows the changes.

The last force push apart from updating EDK revision (and rebasing on dasharo just to not lag behind) extends firmware information to include firmware size.

[SergiiDmytruk]

Last force push:

• rebase on newer dasharo
• update EDK hash to point to https://github.com/Dasharo/edk2/pull/154
• add buffer allocation fix in https://github.com/Dasharo/coreboot/pull/509/commits/e4fcc9be50795b13e7c5836cbc69dcd07d528499 (to be squashed later)
• update EDK-related part of build system to enable capsules

[SergiiDmytruk]

Force-push: rebase to squash and update one of commit messages, also sync top-most commit with the Gerrit.

[SergiiDmytruk]

Force-push:

• update EDK's commit hash
• switch define from CAPSULE_ENABLE to CAPSULE_SUPPORT because that's what UefiPayloadPkg is using (despite tianocore's wiki) and that's how changes were sent upstream

[SergiiDmytruk]

Force-push:

• rebase
• update EDK2 revision (see https://github.com/Dasharo/edk2/pull/147#issuecomment-2336841445)

[SergiiDmytruk]

Force-push:

• rebase (picks up boot logo for Q35)
• resolve conflicts
• point EDK revision at https://github.com/Dasharo/edk2/pull/166 so CI artifacts can be used to test it

[SergiiDmytruk]

Force-push:

• rebase
• update revision of EDK2
• squash coalescing fixes
• make whole flash accessible to Fast SPI

[SergiiDmytruk]

Force-push:

• rebase
• squash recent commits
• update EDK2 revision

@macpijan, you didn't update CONFIG_DRIVERS_EFI_MAIN_FW_VERSION in configs, was that intentional? The last byte should be changed to 0x80 for a release (so that release version is bigger than any RC version).

@SergiiDmytruk @krystian-hebel I was simply not aware of this being also needed right now.

If we need to fix it, we can still do it I guess.

[SergiiDmytruk]

CI complains about it:

config.msi_ms7d25_ddr4: CONFIG_LOCALVERSION doesn't match CONFIG_DRIVERS_EFI_MAIN_FW_VERSION
                        v1.1.4 != v1.1.4-rc3 (0x01010403)
config.msi_ms7d25_ddr5: CONFIG_LOCALVERSION doesn't match CONFIG_DRIVERS_EFI_MAIN_FW_VERSION
                        v1.1.4 != v1.1.4-rc3 (0x01010403)
config.msi_ms7e06_ddr4: CONFIG_LOCALVERSION doesn't match CONFIG_DRIVERS_EFI_MAIN_FW_VERSION
                        v0.9.2 != v0.9.2-rc3 (0x00090203)
config.msi_ms7e06_ddr5: CONFIG_LOCALVERSION doesn't match CONFIG_DRIVERS_EFI_MAIN_FW_VERSION
                        v0.9.2 != v0.9.2-rc3 (0x00090203)

We don't rely on it in code and capsule updates should be fine, so it's not a hard requirement if there is any cost to updating configs again.

[krystian-hebel]

I've updated the configs as a new rebase was needed anyway. When CI builds pass ~~this PR can be merged~~ https://github.com/Dasharo/edk2/pull/147 will have to be merged before this one, and it may also need a rebase...

[krystian-hebel]

After consulting with Beata, I've restored this PR to msi_ms7d25_v1.1.4-rc3 with just a change to local version and CONFIG_DRIVERS_EFI_MAIN_FW_VERSION. The release tag is supposed to be put on it, however we would have to keep the branch (not safe, someone may remove it) or tag (safer) edk2 version that this PR points to. Otherwise, after rebasing https://github.com/Dasharo/edk2/pull/147 the hash will change, and it would be impossible to build this release. (This happened before, for Q35 v0.2.0, it can no longer be built from the release tag).

Are you sure, seems to build? https://github.com/Dasharo/edk2/commit/11b26796145e29b2ceeb5a00b130f81246115159 is there and it's part of some branches/tags.

Huh, I must've be mistaken...
