* pci: Add functions to update PCI configuration registersSimon Glass2016-03-17-0/+23
| | | | | | | | | It is common to read a config register value, clear and set some bits, then write back the updated value. Add functions to do this in one step, for convenience. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

| | | | | | | | | | We can use GPIOs as binary digits for reading 'strapping' values. Each GPIO is assigned a single bit and can be set high or low on the circuit board. We already have a legacy function for reading these values. Add one that supports driver model. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

* ti_armv7_common: env: Add NFS loading support to default enviromentAndrew F. Davis2016-03-15-0/+6
| | | | | | | | | | | NFS loading is similar to net loading except initial files are loaded over NFS instead of TFTP, this removes the need for multiple different protocol servers running on the host and allows the use of a single network file system containing boot related files in their usual in-filesystem directory. Add defaults for this boot style here. Signed-off-by: Andrew F. Davis <afd@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>

* 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 Graf2016-03-15-0/+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>

* 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.

* efi_loader: Implement memory allocation and mapAlexander Graf2016-03-15-0/+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 Graf2016-03-15-0/+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 Graf2016-03-15-0/+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 boot time servicesAlexander Graf2016-03-15-0/+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.

* arm64: Make full va map code more dynamicAlexander Graf2016-03-15-8/+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>
