* efi_loader: Pass proper device path in on bootAlexander Graf2016-03-151-0/+10
| | | | | | | | | | | | | | | | | 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>
* arm64: Replace fdt_name env variables with fdtfileAlexander Graf2016-03-153-8/+8

* efi_loader: Add distro boot script for removable mediaAlexander Graf2016-03-151-1/+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.

* efi_loader: Implement memory allocation and mapAlexander Graf2016-03-151-0/+19
| | | | | | | | | | | | | | | | | | | 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 disk interfacesAlexander Graf2016-03-151-0/+2
| | | | | | | | | | | | | | | A EFI applications usually want to access storage devices to load data from. This patch adds support for EFI disk interfaces. It loops through all block storage interfaces known to U-Boot and creates an EFI object for each existing one. EFI applications can then through these objects call U-Boot's read and write functions.

* efi_loader: Add runtime servicesAlexander Graf2016-03-151-0/+17
| | | | | | | | | | | | | | | | | 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.

* efi_loader: Add console interfaceAlexander Graf2016-03-151-0/+5
| | | | | | | | | | | | | | One of the basic EFI interfaces is the console interface. Using it an EFI application can interface with the user. This patch implements an EFI console interface using getc() and putc(). Today, we only implement text based consoles. We also convert the EFI Unicode characters to UTF-8 on the fly, hoping that everyone managed to jump on the train by now.

* efi_loader: Add boot time servicesAlexander Graf2016-03-151-0/+85
| | | | | | | | | | | | | | When an EFI application runs, it has access to a few descriptor and callback tables to instruct the EFI compliant firmware to do things for it. The bulk of those interfaces are "boot time services". They handle all object management, and memory allocation. This patch adds support for the boot time services and also exposes a system table, which is the point of entry descriptor table for EFI payloads.

* arm64: Make full va map code more dynamicAlexander Graf2016-03-151-8/+6
| | | | | | | | | | | | | | | | | | | 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>

As both bits are contradictory, enabling both disables the input, according to the TWL6030 TRM.

This makes the code shorter by avoiding switch() statements and lots of header file declarations. While this does clean up the code it introduces a few code issues with SPL. SPL never needs to print partition information since this all happens from commands. SPL mostly doesn't need to obtain information about a partition either, except in a few cases. Add these cases so that the code will be dropped from each partition driver when not needed. This avoids code bloat. I think this is still a win, since it is not a bad thing to be explicit about which features are used in SPL. But others may like to weigh in.
