From 50632878bf9dbae54fac4b48070482531002a290 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Thu, 28 Jan 2021 13:04:06 +0100 Subject: device/Kconfig: Introduce MMCONF_LENGTH This is necessary because ASL Memory32Fixed values cannot contain operations, even if they can be evaluated to constants. Add a sanity check in pci_mmio_cfg.h to ensure consistency with MMCONF_BUS_NUMBER.
