* efi_loader: disk: Sanitize exposed devicesAlexander Graf2016-08-08-1/+5
| | | | | | | | | | | | When a target device is 0 bytes long, there's no point in exposing it to the user. Let's just skip them. Also, when an offset is passed into the efi disk creation, we should remove this offset from the total number of sectors we can handle. This patch fixes both things.

* efi_loader: disk: Fix CONFIG_BLK breakageAlexander Graf2016-08-08-7/+11
| | | | | | | | | | | | | | | When using CONFIG_BLK, there were 2 issues: 1) The name we generate the device with has to match the name we set in efi_set_bootdev() 2) The device we pass into our block functions was wrong, we should not rediscover it but just use the already known pointer. This patch fixes both issues. Signed-off-by: Alexander Graf <agraf@suse.de>
* efi_loader: Move to normal debug infrastructureAlexander Graf2016-06-06-7/+4
| | | | | | | | | | | | We introduced special "DEBUG_EFI" defines when the efi loader support was new. After giving it a bit of thought, turns out we really didn't have to - the normal #define DEBUG infrastructure works well enough for efi loader as well. So this patch switches to the common debug() and #define DEBUG way of printing debug information. Signed-off-by: Alexander Graf <agraf@suse.de>

* | efi_loader: Add bounce buffer supportAlexander Graf2016-05-27-9/+61
|/ | | | | | | | | | | | Some hardware that is supported by U-Boot can not handle DMA above 32bits. For these systems, we need to come up with a way to expose the disk interface in a safe way. This patch implements EFI specific bounce buffers. For non-EFI cases, this apparently was no issue so far, since we can just define our environment variables conveniently.

* efi_loader: Increase path string to 32 charactersAlexander Graf2016-04-18-2/+2
| | | | | | | | | | | | Whenever we want to tell our payload about a path, we limit ourselves to a reasonable amount of characters. So far we only passed in device names - exceeding 16 chars was unlikely there. However by now we also pass real file path information, so let's increase the limit to 32 characters. That way common paths like "boot/efi/bootaa64.efi" fit just fine. Signed-off-by: Alexander Graf <agraf@suse.de>
* efi_loader: Add el torito supportAlexander Graf2016-04-18-0/+35
| | | | | | | | | | When loading an el torito image, uEFI exposes said image as a raw block device to the payload. Let's do the same by creating new block devices with added offsets for the respective el torito partitions. Signed-off-by: Alexander Graf <agraf@suse.de>
* efi_loader: Split drive add into functionAlexander Graf2016-04-18-37/+47

* efi_loader: Pass proper device path in on bootAlexander Graf2016-03-15-6/+0
| | | | | | | | | | | | | | | | | 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 disk interfacesAlexander Graf2016-03-15-0/+218
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.
