Subject: [PATCH 2/2] hw/ppc/ppc440_uc: Remove dead l2sram_update_mappings()
Date: Wed, 11 Oct 2023 14:43:12 +0200 [thread overview]
Message-ID: <20231011124312.60476-3-philmd@linaro.org> (raw)
In-Reply-To: <20231011124312.60476-1-philmd@linaro.org>
Apparently l2sram_update_mappings() bit-rotted over time,
when defining MAP_L2SRAM we get:
hw/ppc/ppc440_uc.c:83:17: error: no member named 'isarc' in 'struct ppc4xx_l2sram_t'
if (l2sram->isarc != isarc ||
~~~~~~ ^

Remove that dead code.
