Subject: [PATCH 3/3] ARM: qcom: merge remaining subplatforms into sensible Kconfig entry
Date: Thu, 7 Dec 2023 15:55:00 +0300 [thread overview]
Message-ID: <20231207125500.3322229-4-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20231207125500.3322229-1-dmitry.baryshkov@linaro.org>
Three remaining Qualcomm platforms have special handling of the
TEXT_OFFSET to reserve the memory at the beginnig of the system RAM, see
the commit 9e775ad19f52 ("ARM: 7012/1: Set proper TEXT_OFFSET for newer
MSMs"). This is required for older platforms like IPQ40xx, MSM8x60,
MSM8960 and APQ8064 and is compatible with other 32-bit Qualcomm
platforms.
