Subject: [U-Boot] [PATCH 1/2] pci: Only link pci_rom.o in some cases
Date: Tue, 26 Nov 2019 20:40:59 -0500	[thread overview]
Message-ID: <20191127014100.29733-1-trini@konsulko.com> (raw)

The content of pci_rom.c is only used in a few cases.  Only build and
link in these cases to avoid a global variable as gcc doesn't always
discard those when they are unused.
