* x86: Do relocation before clearing BSSSimon Glass2017-02-06-1/+1
| | | | | | | | | | | | | The BSS region may overlap with relocations. If we clear BSS we will overwrite the start of the relocation area. This doesn't matter when running from SPI flash, since it is read-only. But when relocating 64-bit U-Boot from one place in RAM to another, relocation will fail because some of its relocations have been zeroed. To fix this, put the ELF fixup call before the BSS clearing call. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

| | | | | | | | | Adjust the code so that 64-bit startup works. Since we don't need to do CAR changes in U-Boot proper anymore (they are done in SPL) we can simplify the flow and return normally from board_init_f().

* board_f: Add a mach_cpu_init callbackPaul Burton2016-09-21-0/+6
| | | | | | | | | | | | | | | | Currently we have a mismash of architectures which use arch_cpu_init from architecture-wide code (arc, avr32, blackfin, mips, nios2, xtensa) and architectures which use arch_cpu_init from machine/SoC level code (arm, x86). In order to clean this mess up & allow for both use cases, introduce a new mach_cpu_init callback which is run immediately after arch_cpu_init. This will allow for architectures to have arch-wide code without needing individual machines to all implement their own arch_cpu_init with a call to some common function.

* x86: Allow use of serial soon after relocationSimon Glass2016-03-17-0/+7
| | | | | | | | | | | | | | | At present on x86 machines with use cache-as-RAM, the memory goes away just before board_init_r() is called. This means that serial drivers are no-longer unavailable, until initr_dm() it called, etc. Any attempt to use printf() within this period will cause a hang. To fix this, mark the serial devices as 'unavailable' when it is no-longer available. Bring it back when serial_initialize() is called.

PRAM offers memory at the top of u-boot memory, not necessarily the real end of memory for systems with very large DDR. Using the end of memory simplifies MMU setup and avoid memory fragmentation.

* console: Add a console bufferSimon Glass2015-11-19-0/+10
| | | | | | | | | | | | | | | | | | | It is useful to be able to record console output and provide console input via a buffer. This provides sandbox with the ability to run a command and check its output. If the console is set to silent then no visible output is generated. This also provides a means to fix the problem where tests produce unwanted output, such as errors or warnings. This can be confusing. We can instead set the console to silent and record this output. It can be checked later in the test if required. It is possible that this may prove useful for non-test situations. For example the console output may be suppressed for normal operations, but recorded and stored for access by the OS. That feature is not implemented at present.
