2021-12-09efi: Add a media/block driver for EFI block devicesSimon Glass3-0/+126
Add a block driver which handles read/write for EFI block devices. This driver actually already exists ('efi_block') but is not really suitable for use as a real U-Boot driver: - The operations do not provide a udevice - The code is designed for running as part of EFI loader, so uses EFI_PRINT() and EFI_CALL(). - The bind method probes the device, which is not permitted - It uses 'EFI' as its parent device The new driver is more 'normal', just requiring its platform data be set up in advance.

2021-07-19usb: Enforce DM_USB migration for USB_HOST devices.Tom Rini1-1/+1
As the deadline for migration to DM_USB, when using a USB host controller has now gone two years past the deadline, enforce migration. This is done by: - Ensuring that all host controller options (other than the very legacy old MUSB ones) now select USB_HOST. USB_HOST now enforces DM_USB and OF_CONTROL. - Remove other parts of Kconfig logic that had platforms pick DM_USB. - To keep Kconfig happy, have some select statements test for USB_HOST as well. - Re-order some Kconfig entries and menus so that we can cleanly pick host or gadget roles. For the various HCD options that have platform glue options, group them together and update dependencies in some cases. - As SPL_DM_USB is not required, on platforms that had not yet enabled it, disable it.

Fixes IDE issues found on the Malta board under Qemu: 1) DMA implied commands were sent to the controller in stead of the PIO variants. The rest of the code is DMA free and written for PIO operation. 2) direct pointer access was used to read and write the registers instead of the inb/inw/outb/outw functions/macros. Registers don't have to be memory mapped and ATA_CURR_BASE() does not have to return an offset from address zero. 3) Endian isues in ide_ident() and reading/writing data in general.

2021-03-27sandbox: Provide a way to bind fixed/removeable devicesSimon Glass1-4/+4
At present when a file is bound to a host device it is always marked as removeable. Arguably the device is removeable, since it can be unbound at will. However while it is bound, it is not considered removable by the user. Also it is useful to be able to model both fixed and removeable devices for code that distinguishes them. Add a -r flag to the 'host bind' command and plumb it through to provide this feature. Signed-off-by: Simon Glass <sjg@chromium.org>

This reverts commit 0ebe112d09b48230ba4be833cd3504b06997d9a4. Most block devices have only one hwpart. Multiple hwparts only found used by eMMC devices in u-boot. The mmc driver do blk_dselect_hwpart() at the beginning of mmc_bread() which causes block cache being invalidated too frequently and makes block cache useless. So it's not a good idea to put blkcache_invalidate() in the common functions. It should be called inside mmc_select_hwpart().

2019-07-18blk: Invalidate block cache when switching hwpartWeijie Gao1-2/+12
Some storage devices have multiple hw partitions and both address from zero, for example eMMC. However currently block cache invalidation only applies to block write/erase. This can cause a problem that data of current hw partition is cached before switching to another hw partition. And the following read operation of the latter hw partition will get wrong data when reading from the addresses that have been cached previously. To solve this problem, invalidate block cache after a successful select_hwpart operation. Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini6-13/+6
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
