* x86: Kconfig: Add location options for 16/32-bit initSimon Glass2017-02-06-0/+40
| | | | | | | | | | | | | | | | | | At present all 16/32-bit init is controlled by CONFIG_X86_RESET_VECTOR. If this is enabled, then U-Boot is the 'first' boot loader and handles execution from the reset vector through to U-Boot's command prompt. If it is not enabled then U-Boot starts at the 32-bit entry and skips most of its init, assuming that the previous boot loader has done this already. With the move to suport 64-bit operation, we have more cases to consider. The 16-bit and 32-bit init may be in SPL rather than in U-Boot proper. Add Kconfig options which control the location of the 16-bit and the 32-bit init. These are not intended to be user-setting except for experimentation. Their values should be determined by whether 64-bit U-Boot is used. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

* libfdt: replace ARCH_FIXUP_FDT with ARCH_FIXUP_FDT_MEMORYMasahiro Yamada2016-12-02-0/+5
| | | | | | | | | | | | | | | | | | Commit e2f88dfd2d96 ("libfdt: Introduce new ARCH_FIXUP_FDT option") allows us to skip memory setup of DTB, but a problem for ARM is that spin_table_update_dt() and psci_update_dt() are skipped as well if CONFIG_ARCH_FIXUP_FDT is disabled. This commit allows us to skip only fdt_fixup_memory_banks() instead of the whole of arch_fixup_fdt(). It will be useful when we want to use a memory node from a kernel DTB as is, but need some fixups for Spin-Table/PSCI.

* efi_loader: Allow to compile helloworld.efi w/o bundling itAlexander Graf2016-11-27-2/+2
| | | | | | | | | | | | | | | | | Today we can compile a self-contained hello world efi test binary that allows us to quickly verify whether the EFI loader framwork works. We can use that binary outside of the self-contained test case though, by providing it to a to-be-tested system via tftp. This patch separates compilation of the helloworld.efi file from including it in the u-boot binary for "bootefi hello". It also modifies the efi_loader test case to enable travis to pick up the compiled file. Because we're now no longer bloating the resulting u-boot binary, we can enable compilation always, giving us good travis test coverage.

* ls2080: Exit dpaa only right before exiting U-BootAlexander Graf2016-11-17-0/+5
| | | | | | | | | | | | | | | | | | | | | 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]
