* dm: usb: Do not reprobe usb hosts on "usb tree" commandHans de Goede2016-04-10-2/+6
| | | | | | | | | | | | Some usb hosts may have failed to probe on "usb start", i.e. an otg host without an otg-host cable plugged in. "usb tree" would cause the probe method of these hosts to get called again, something which should only happen on "usb reset". This commit fixes this.

* drivers: block: add block device cacheEric Nelson2016-04-01-0/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a block device cache to speed up repeated reads of block devices by various filesystems. This small amount of cache can dramatically speed up filesystem operations by skipping repeated reads of common areas of a block device (typically directory structures). This has shown to have some benefit on FAT filesystem operations of loading a kernel and RAM disk, but more dramatic benefits on ext4 filesystems when the kernel and/or RAM disk are spread across multiple extent header structures as described in commit fc0fc50. The cache is implemented through a minimal list (block_cache) maintained in most-recently-used order and count of the current number of entries (cache_count). It uses a maximum block count setting to prevent copies of large block reads and an upper bound on the number of cached areas. The maximum number of entries in the cache defaults to 32 and the maximum number of blocks per cache entry has a default of 2, which has shown to produce the best results on testing of ext4 and FAT filesystems. The 'blkcache' command (enabled through CONFIG_CMD_BLOCK_CACHE) allows changing these values and can be used to tune for a particular filesystem layout. Signed-off-by: Eric Nelson <eric@nelint.com>

* efi_loader: Pass proper device path in on bootAlexander Graf2016-03-15-9/+27
| | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | 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.

We need to make sure this option is not enabled in SPL by this change. Also this option is enabled automatically in the host builds by defining CONFIG_FIT in the image.h file.

This change sets file size limitation to the DFU internal buffer size. Since u-boot is not supporting interrupts and seek on file systems, it becomes challenging to store large file appropriately. To reproduce this error - create large file (around 26 MiB) and sent it to the target board. Lets examine the flow of USB transactions: 0. DFU uses EP0 with 64B MPS [Max Packet Size] 1. Send file - OUT (PC->target) - dat_26MiB.img is sent with 4096 B transactions 2. Get status - OUT (PC->target) - wait for DFU_STATE_dfuDNLOAD_IDLE (0x05) sent from target board - IN transaction (target->PC) 3. The whole file content is sent to target - OUT (PC->target) with ZLP [Zero Length Packet] Now the interesting part starts: 4. OUT (PC->target) Setup transaction (request to share DFU state) 5. IN (target->PC) - reply the current DFU state - In the UDC driver the req->completion (with dfu_flush) is called after successful IN transfer. - The dfu_flush() (called from req->completion callback) saves the whole file at once (u-boot doesn't support seek on fs). Such operation takes considerable time. When the file is large - e.g. 26MiB - this time may be more than 5 seconds. 6. OUT (PC->target) - ZLP, is send in the same time when dfu_flush() writes data to eMMC memory. The dfu-util application has hard coded timeout on USB transaction completion set to 5 seconds (it uses libusb calls). When the file to store is large (e.g. 26 MiB) the time needed to write it may excess the dfu-util timeout and following error message will be displayed: "unable to read DFU status" on the HOST PC console. This change is supposed to leverage DFU's part responsible for storing files on file systems. Other DFU operations - i.e. raw/partition write to NAND and eMMC should work as before. The only functional change is the error reporting. When dfu_flush() fails the u-boot prompt will exit with error information and dfu-util application exits afterwards as well.

* itest: allow map_physmem to return 0 in limited casesStephen Warren2016-02-09-1/+1
| | | | | | | | | | | | | | | | | | | | | | On some systems, RAM starts at address 0. If the user executes itest against address 0 on such a system, it will call map_physmem(0, ...) which will return 0 back; mapping only changes the address on sandbox. This causes itest to believe map_physmem() has failed, and hence fails the comparison. Fix itest so that it allows map_physmem() to return 0 /if/ the orignal address passed to it was also 0. This fixes "tegra-uboot-flasher flash" on Tegra20. This has the disadvantage that on sandbox, failed mapping attempts for address 0 are not detected. Instead, should the code only call map_physmem() on sandbox? Or, should map_physmem() return its error status some other way. Or, should the special case only be allowed on systems where the base of RAM is 0 somehow?

| * Implement "pci enum" command for CONFIG_DM_PCIStephen Warren2016-01-28-13/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With CONFIG_DM_PCI enabled, PCI buses are not enumerated at boot, as they are without that config option enabled. No command exists to enumerate the PCI buses. Hence, unless some board-specific code causes PCI enumeration, PCI-based Ethernet devices are not detected, and network access is not available. This patch implements "pci enum" in the CONFIG_DM_PCI case, thus giving a mechanism whereby PCI can be enumerated. do_pci()'s handling of case 'e' is moved into a single location before the dev variable is assigned, in order to skip calculation of dev. The enum sub-command doesn't need the dev value, and skipping its calculation avoids an irrelevant error being printed. Using a command to initialize PCI like this has a disadvantage relative to enumerating PCI at boot. In particular, Ethernet devices are not probed during PCI enumeration, but only when used. This defers setting variables such as ethact, ethaddr, etc. until the first network-related command is executed. Hopefully this will not cause further issues. Perhaps in the long term, we need a "net start/enum" command too?
