I confirm on focal.
WORKAROUND, install linux-firmware package from Impish (1.201) instead of one
from focal (1.187)
The many kernel errors about PCI devices dissapear during the boot time. Not
sure about the real impact on the system itself.

Title:
Missing firmware files, in Ubuntu 20.04 LTS, for initramfs, when it
loads i915
Status in initramfs-tools package in Ubuntu:
Invalid
Status in linux-firmware package in Ubuntu:
Confirmed
Bug description:
Dear all,
I can see that the linux-firmware is missing firmware files, in Ubuntu
20.04.1 LTS, for initramfs, when it loads i915.
Package: linux-firmware 1.187.15
It contains the following files, for the module i915:
i915/tgl_dmc_ver2_04.bin 2019-09-13 installed
i915/tgl_dmc_ver2_06.bin 2020-03-04 installed
i915/tgl_dmc_ver2_08.bin 2020-08-13 installed
i915/tgl_guc_35.2.0.bin 2019-11-06 installed
i915/tgl_huc_7.0.12.bin 2020-03-04 installed
i915/tgl_huc_7.0.3.bin 2019-11-06 installed
Package: linux-firmware
MUST at least contain the following files, for the module i915:
i915/tgl_huc_7.5.0.bin 2020-08-13 i915: Add HuC
firwmare v7.5.0 for TGL
as the module asks for it, during 'update-initramfs', to avoid:
W: Possible missing firmware /lib/firmware/i915/tgl_huc_7.5.0.bin for module
i915
But it COULD also contain :
i915/tgl_dmc_ver2_12.bin 2021-07-28 i915: Add v2.12 DMC for TGL
i915/tgl_guc_49.0.1.bin 2020-11-24 i915: Add GuC firmware
v49.0.1 for all platforms
i915/tgl_guc_62.0.0.bin 2021-06-29 firmware/i915/guc: Add
GuC v62.0.0 for all platforms
i915/tgl_huc_7.9.3.bin 2021-06-29 firmware/i915/guc: Add
HuC v7.9.3 for TGL & DG1
Source:
$ modprobe --show-depends --ignore-install i915
...
insmod /lib/modules/5.10.0-1038-oem/kernel/drivers/gpu/drm/i915/i915.ko
$ modinfo -F firmware
/lib/modules/5.10.0-1038-oem/kernel/drivers/gpu/drm/i915/i915.ko
...
i915/tgl_dmc_ver2_08.bin
i915/tgl_guc_35.2.0.bin
i915/tgl_huc_7.5.0.bin
Actual result:
$ sudo update-initramfs -u
W: Possible missing firmware /lib/firmware/i915/tgl_huc_7.5.0.bin for module
i915
Expected result:
No Warning. and the firmware "i915/tgl_huc_7.5.0.bin" loaded for module i915
