2017-04-05board_f: Make init_helpers genericSimon Glass
This header file is used by two archs. It could be used by all of them since it allows the cache to be on during relocation. Move it into a generic file. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-04-05Move dram_init_banksize() to a common headerSimon Glass
This is an weak function present on all archs so we should have it in the common header file. Remove it from arch-specific headers and add a function comment. Signed-off-by: Simon Glass <sjg@chromium.org>

2017-04-05board_f: x86: Rename x86_fsp_init() to arch_fsp_init()Simon Glass
While x86 is the only user and this could in principle be moved to arch_cpu_init() there is some justification for this being a separate call. It provides a way to handle init which is not CPU-specific, but must happen before the CPU can be set up. Rename the function to be more generic.

2016-11-17ls2080: Exit dpaa only right before exiting U-BootAlexander Graf
On ls2080 we have a separate network fabric component which we need to shut down before we enter Linux (or any other OS). Along with that also comes configuration of the fabric using a description file. Today we always stop and configure the fabric in the boot script and (again) exit it on device tree generation. This works ok for the normal booti case, but with bootefi the payload we're running may still want to access the network. So let's add a new fsl_mc command that defers configuration and stopping the hardware to when we actually exit U-Boot, so that we can still use the fabric from an EFI payload. For existing boot scripts, nothing should change with this patch. Signed-off-by: Alexander Graf <agraf@suse.de> Reviewed-by: York Sun <york.sun@nxp.com> [agraf: Fix x86 build]

2016-05-23x86: acpi: Switch to ACPI mode by ourselves instead of requested by OSPMBin Meng
Per ACPI spec, during ACPI OS initialization, OSPM can determine that the ACPI hardware registers are owned by SMI (by way of the SCI_EN bit in the PM1_CNT register), in which case the ACPI OS issues the ACPI_ENABLE command to the SMI_CMD port. The SCI_EN bit effectively tracks the ownership of the ACPI hardware registers. However since U-Boot does not support SMI, we report all 3 fields in FADT (SMI_CMD, ACPI_ENABLE, ACPI_DISABLE) as zero, by following the spec who says: these fields are reserved and must be zero on system that does not support System Management mode. U-Boot seems to behave in a correct way that the ACPI spec allows, at least Linux does not complain, but apparently Windows does not think so. During Windows bring up debugging, it is observed that even these 3 fields are zero, Windows are still trying to issue SMI with hardcoded SMI port address and commands, and expecting SCI_EN to be changed by the firmware. Eventually Windows gives us a BSOD (Blue Screen of Death) saying ACPI_BIOS_ERROR and refuses to start. To fix this, turn on the SCI_EN bit by ourselves. With this patch, now U-Boot can install and boot Windows 8.1/10 successfully with the help of SeaBIOS using legacy interface (non-UEFI mode).
