From: Vladimir Zapolskiy Date: Sun, 27 Nov 2016 22:15:25 +0000 (+0200) Subject: sh4: use single u-boot linker script for all boards X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=3f8b5391ec531adec6fa7602aeb8894b7a23d44d;p=u-boot.git sh4: use single u-boot linker script for all boards 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.
