PS4, Line 9: Add SOC_INTEL_CSE_LITE_COMPRESS_ME_RW Kconfig to enable compression on
           : ME_RW blobs.
           : Select the Kconfig to add LZMA compressed ME_RW blobs to ME_RW_A/B
           : regions.
           : On ADL-N, this results in savings of ~665KB in each of ME_RW_A/B
           : regions.

PS4, Line 89: LZMA
> Just curious, have you benchmarked LZ4 here too (both decompression time and compression ratio) ?

With LZMA:
FMAP REGION: ME_RW_A
Name                           Offset     Type           Size   Comp
me_rw                          0x0        raw           1279068 LZMA (2002944 decompressed)

With LZ4:
FMAP REGION: ME_RW_A
Name                           Offset     Type           Size   Comp
me_rw                          0x0        raw           1365742 LZ4  (2002944 decompressed)
