From 2360409d9c1defb329cdcf8108ddb3501c467a93 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Pali=20Roh=C3=A1r?= Date: Wed, 29 Mar 2023 21:03:30 +0200 Subject: [PATCH] arm: mvebu: Remove A38x BOOT_FROM_UART_ALT 0x3f constant MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit A385 BootROM treats strapping configuration 0x3f as invalid. When booting fails (e.g. because of invalid configuration) then BootROM fallbacks to UART booting. Detecting BootROM fallback to UART booting is implemented in U-Boot since commit 2fd4284051e3 ("ARM: mach-mvebu: handle fall-back to UART boot"). So there is no need to define BOOT_FROM_UART_ALT constant and special handling for it anymore, remove it. This change effectively revers commit f3a88e2ca17a ("arm: mvebu: fix boot from UART on ClearFog Base").
