From 8856d613cb79876e1b1e1ef01b7507725810b7c5 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 15 Jul 2023 21:39:09 -0600 Subject: [PATCH] x86: Refactor table-writing code a little The implementation of write_tables() is confusing because it uses the rom_table_start variable as the address pointer as it progresses. Rename it to rom_addr to make the code clearer. Move the rom_table_end variable into the block where it is used. Also update logging to use the ACPI category, now that it is available.
