Subject: [U-Boot] [RESEND][PATCH 13/24] sh4: use single u-boot linker script for all boards
Date: Mon, 28 Nov 2016 00:15:25 +0200	[thread overview]
Message-ID: <20161127221536.9577-14-vz@mleia.com> (raw)
In-Reply-To: <20161127221536.9577-1-vz@mleia.com>

Three supported SH4/SH4A boards with the bootloader image stored on
SPI flash have own flavour of a linker script, in turn they are equal
among each other. The only difference is that the text from
lowlevel_init.o is placed right after start.o, which makes sense.

Note that .bss section is not marked as NOLOAD, because for about
10 years this is a default option of a GNU linker, either the
attribute is found or not the resulting image file is the same.
