Date: Wed, 12 Aug 2020 02:15:04 +0200 From: Paul Cercueil <paul@...pouillou.net> To: Thomas Bogendoerfer <tsbogend@...ha.franken.de> Cc: Paul Burton <paulburton@...nel.org>, Krzysztof Kozlowski <krzk@...nel.org>, 周琰杰 <zhouyanjie@...yeetech.com>, od@...c.me, linux-kernel@...r.kernel.org, linux-mips@...r.kernel.org, Paul Cercueil <paul@...pouillou.net> Subject: [PATCH v2 07/13] MIPS: generic: Support booting with built-in or appended DTB The plat_get_fdt() checked that the kernel was booted using UHI before reading the 'fw_passed_dtb' variable. However, this variable is also set when the kernel has been appended, or when it has been built into the kernel. Support these usecases by removing the UHI check.
