From 397626ced67427538d85aded42135e20a7fb393a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Pali=20Roh=C3=A1r?= Date: Mon, 8 Aug 2022 19:13:43 +0200 Subject: [PATCH] arm: mvebu: Define env_sf_get_env_addr() for all Armada boards in SPL MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit SPI0 CS0 Flash is mapped to address range 0xD4000000 - 0xD7FFFFFF by BootROM. Proper U-Boot removes this direct mapping. So it is available only in SPL. This applies for all 32-bit Armada BootROMs. SPL mvebu code is used only on 32-bit Armada SoCs. So move env_sf_get_env_addr() function from Turris Omnia board to common SPL mvebu code and add proper checks for SPI0 CS0.
