From f643141728a4aebd64e1bd35e941cd2447651821 Mon Sep 17 00:00:00 2001 From: Kapil Porwal Date: Mon, 17 Nov 2025 22:40:05 +0530 Subject: [PATCH] mb/google/fatcat: Option to enable monochrome VGA mode 12 Update the Fatcat mainboard Kconfig to select FSP_VGA_MODE12_MONOCHROME. The FSP_VGA_MODE12_MONOCHROME option enables the use of a minimal 1-bit-per-pixel (1bpp) framebuffer for early sign-of-life (eSOL) messages, which significantly reduces the DRAM size required for the framebuffer in romstage. Key changes: - Deselect FSP_VGA_MODE12 for CONFIG_FATCAT_VGA_MODE12_SUPPORT. - Select FSP_VGA_MODE12_MONOCHROME instead. BUG=b:406725440 TEST=Verify VGA text rotation on Google/Felino.
