add support for the at91sam9260 based board smartweb from siemens. SPL is used without serial support, as this SoC has only 4k sram for running SPL. Here a U-Boot bootlog:
RomBOOT
U-Boot 2015.07-rc2-00109-g4ae828c (Jun 15 2015 - 09:31:16 +0200)
CPU: AT91SAM9260 Crystal frequency: 18.432 MHz CPU clock : 198.656 MHz Master clock : 99.328 MHz Watchdog enabled DRAM: 64 MiB WARNING: Caches not enabled NAND: 256 MiB In: serial Out: serial Err: serial Net: macb0 Hit any key to stop autoboot: 0 U-Boot>
As this board is based on sam9260 SoC with 4k sram only, SPL must be small, so SPL is compiled without serial support. Therefore the code needs here and there some small fixes to support SPL compile without serial support.
Changes in v2: - add comment from Tom Rini: - do not delete __maybe_unused - remove preloader_console_init() in non SERIAL case - squashed patch "lib/display_options: fix compiler warnings" into this patch. - add Acked-by from Scott Wood - rebase to 7853d76b0bdab9b
