Subject: [PATCH v2 3/3] ARM: qcom: merge remaining subplatforms into sensible Kconfig entry
Date: Sat, 16 Dec 2023 18:27:00 +0200	[thread overview]
Message-ID: <20231216162700.863456-4-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20231216162700.863456-1-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.
