Firmware for the Lenovo ThinkPad P15v, machine types 21A9 and 21AA, on LCFC board NM-D552, with dumps for chips U2001 and U4402 and a 32 MB capacity noted. Two designators mean separate flash images, so write each file to the matching location only. A 32 MB image suits a 256 Mbit SPI chip. Read and store the original contents first, since ThinkPad flashes hold serial and security data, and confirm the board number and chip size agree before programming.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
