History

Trent Piepho f62fb99941 Fix all linker script to handle all rodata sections A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata" to get all rodata linker section gcc has now and might add in the future. However, '(.rodata)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: (.text) . = ALIGN(16); (.rodata) (.rodata.str1.4) (.eh_frame) I change this to: (.text) . = ALIGN(16); (.eh_frame) (SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is.

README

To configure for the current (Rev 3.x) ADS5121
	make ads5121_config
This will automatically include PCI, the Real Time CLock, add backup flash
ability and set the correct frequency and memory configuration.

To configure for the older Rev 2 ADS5121 type (this will not have PCI)
	make ads5121_rev2_config
