* common/board_f: factor out reserve_stacksAndreas Bießmann2015-02-17-0/+75

| * sandbox: Adjust the order of the NO_SDL checkSimon Glass2015-02-15-6/+6
| | | | | | | | | | | | | | | | | | | | | | An option is provided to avoid using SDL in U-Boot sandbox (and drop support for the LCD). However the check in the Makefile is too late and warnings are printed even if NO_SDL=y is given. Adjust the order to avoid this warning.

| * sandbox: Return '-c command' exit value as sandbox exit codeJoe Hershberger2015-02-15-22/+4
| | | | | | | | | | | | | | | | | | | | | | | | When a command is passed into sandbox using the '-c' argument the command is run directly. This is most helpful when running tests (such as test-dm.sh). Previously the exit code was an unused enum. Change it to be the actual return code from the command so that the script calling sandbox can know if the command succeeded (tests passed). Also remove the now completely unused "exit_state" in sandbox. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we have src, div and pre-div mask bits defined corresponding to peripherals, calculation of clock specific to I2C appears redundant and confusing. Using clk_bit_info struct we can write calculations generic to all peripherals which makes code easy to understand and free from peripheral specific exceptions.

| * | arc: introduce U-Boot port for ARCv2 ISAAlexey Brodkin2015-02-13-3/+335
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARC HS and ARC EM are new cores based on ARCv2 ISA which is binary incompatible with ISAv1 (AKA ARCompact). Significant difference between ISAv2 and v1 is implementation of interrupt vector table. In v1 it is implemented in the same way as on many other architectures - as a special location where user may put whether code executed in place (if machine word of space is enough) or jump to a full-scale interrupt handler. In v2 interrupt table is just an array of adresses of real interrupt handlers. That requires a separate section for IVT that is not encoded as code by assembler. This change adds support for following cores: * ARC EM6 (simple 32-bit microcontroller without MMU) * ARC HS36 (advanced 32-bit microcontroller without MMU) * ARC HS38 (advanced 32-bit microcontroller with MMU) As a part of ARC HS38 new version of MMU (v4) was introduced. Also this change adds AXS131 board which is the same DW ARC SDP base board but with ARC HS38 CPU tile. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
