* arm, at91: add icache supportHeiko Schocher2016-10-28-0/+30
| | | | | | | | | | | add at least icache support for at91 based boards. This speeds up NOR flash access on an at91sam9g15 based board from 15.2 seconds reading 8 MiB from a SPI NOR flash to 5.7 seconds.

* spl: arm: Make sure to include all of the u_boot_list entriesTom Rini2016-03-16-0/+3
| | | | | | | | | | | | | | Starting with 96e5b03 we use a linker list for partition table information. However since we use this in SPL we need to make sure that the SPL linker scripts include these as well. While doing this, it's best to simply include all linker lists to future proof ourselves.
