* keystone2: env: Set mmc as default boot for k2g-evmYan Liu2016-03-15-1/+4

* keystone2: env: add env script for booting with an initramfs with firmwareMurali Karicheri2016-03-15-3/+17
| | | | | | | | | | | | | | | | | | | | | This patch updates the env script to include a initramfs with firmware loaded and provided to kernel through second argument of bootz command during boot. Defined DEFAULT_FW_INITRAMFS_BOOT_ENV to have all of the required env variables and use it in evm specific config file. The K2 linux drivers for PCIe and NetCP (1G, 10G) requires serdes firmwares. These requires firmware to be available early through the boot process in some cases to satisfy firmware requests from driver. Hence use a small initramfs to provide the same and update boot env to accommodate this in the boot flow. This method is used when rootfs is nfs and ubifs. This fs contains just lib/firmware folder with all required firmware. When rootfs is on initramfs, then the filesystem has the firmware under lib/firmware and this early initramfs is not required and is not used.

* efi_loader: Pass proper device path in on bootAlexander Graf2016-03-15-15/+37
| | | | | | | | | | | | | | | | | EFI payloads can query for the device they were booted from. Because we have a disconnect between loading binaries and running binaries, we passed in a dummy device path so far. Unfortunately that breaks grub2's logic to find its configuration file from the same device it was booted from. This patch adds logic to have the "load" command call into our efi code to set the device path to the one we last loaded a binary from. With this grub2 properly detects where we got booted from and can find its configuration file, even when searching by-partition. Signed-off-by: Alexander Graf <agraf@suse.de>

* efi_loader: Add distro boot script for removable mediaAlexander Graf2016-03-15-1/+46
| | | | | | | | | | | | | | | | | | UEFI defines a simple boot protocol for removable media. There we should look at the EFI (first GPT FAT) partition and search for /efi/boot/bootXXX.efi with XXX being different between different platforms (x86, x64, arm, aa64, ...). This patch implements a simple version of that protocol for the default distro boot script. With this we can automatically boot from valid UEFI enabled removable media. Because from all I could see U-Boot by default doesn't deliver device tree blobs with its firmware, we also need to load the dtb from somewhere. Traverse the same EFI partition for an fdt file that fits our current board so that an OS receives a valid device tree when booted automatically.

* arm64: Allow exceptions to returnAlexander Graf2016-03-15-0/+34
| | | | | | | | | | | | | | Our current arm64 exception handlers all panic and never return to the exception triggering code. But if any handler wanted to continue execution after fixups, it would need help from the exception handling code to restore all registers. This patch implements that help.

* efi_loader: Implement memory allocation and mapAlexander Graf2016-03-15-0/+341
| | | | | | | | | | | | | | | | | | | The EFI loader needs to maintain views of memory - general system memory windows as well as used locations inside those and potential runtime service MMIO windows. To manage all of these, add a few helpers that maintain an internal representation of the map the similar to how the EFI API later on reports it to the application. For allocations, the scheme is very simple. We basically allow allocations to replace chunks of previously done maps, so that a new LOADER_DATA allocation for example can remove a piece of the RAM map. When no specific address is given, we just take the highest possible address in the lowest RAM map that fits the allocation size.

* efi_loader: Add "bootefi" commandAlexander Graf2016-03-15-0/+190
| | | | | | | | | | | | | | | | | | | | | | In order to execute an EFI application, we need to bridge the gap between U-Boot's notion of executing images and EFI's notion of doing the same. The best path forward IMHO here is to stick completely to the way U-Boot deals with payloads. You manually load them using whatever method to RAM and then have a simple boot command to execute them. So in our case, you would do # load mmc 0:1 $loadaddr grub.efi # bootefi $loadaddr which then gets you into a grub shell. Fdt information known to U-boot via the fdt addr command is also passed to the EFI payload.

* efi_loader: Add runtime servicesAlexander Graf2016-03-15-3/+398
| | | | | | | | | | | | | | | | | After booting has finished, EFI allows firmware to still interact with the OS using the "runtime services". These callbacks live in a separate address space, since they are available long after U-Boot has been overwritten by the OS. This patch adds enough framework for arbitrary code inside of U-Boot to become a runtime service with the right section attributes set. For now, we don't make use of it yet though. We could maybe in the future map U-boot environment variables to EFI variables here.

* arm64: Make full va map code more dynamicAlexander Graf2016-03-15-108/+500
| | | | | | | | | | | | | | | | | | | The idea to generate our pages tables from an array of memory ranges is very sound. However, instead of hard coding the code to create up to 2 levels of 64k granule page tables, we really should just create normal 4k page tables that allow us to set caching attributes on 2M or 4k level later on. So this patch moves the full_va mapping code to 4k page size and makes it fully flexible to dynamically create as many levels as necessary for a map (including dynamic 1G/2M pages). It also adds support to dynamically split a large map into smaller ones when some code wants to set dcache attributes. With all this in place, there is very little reason to create your own page tables in board specific files. Signed-off-by: Alexander Graf <agraf@suse.de>
