From 845be5523893e02d8b03f7aa6c4346005c13d377 Mon Sep 17 00:00:00 2001 From: Ahmad Fatoum Date: Mon, 17 Apr 2023 14:51:58 +0200 Subject: lib: genalloc: drop reliance on mmio-sram driver The barebox mmio-sram driver just makes SRAMs available as /dev/sramX devices. The genalloc stub depended on it without selecting CONFIG_SRAM. Instead of making this dependency explicit, just call of_address_to_resource and have no dependency on CONFIG_SRAM at all.
