blk: Support iteration

2021-07-21T16:27:35+00:00

It is useful to be able to iterate over block devices. Typically there
are fixed and removable devices. For security reasons it is sometimes
useful to ignore removable devices since they are under user control.

Add iterators which support selecting the block-device type.

usb: Enforce DM_USB migration for USB_HOST devices.

2021-07-19T01:05:31+00:00

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.

Fix IDE commands issued, fix endian issues, fix non MMIO

2021-04-20T11:31:12+00:00

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. Names
were corrupted and sizes misreported.

Tested malta_defconfig and maltael_defconfig to work again in Qemu.

sandbox: Provide a way to bind fixed/removeable devices

2021-03-27T02:04:31+00:00

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.

sandbox: host bind must close file descriptor

2021-03-04T02:17:25+00:00

Each invocation of the 'host bind' command with a file name argument opens
a file descriptor. The next invocation of the 'host bind' command destroys
the block device but the file descriptor remains open. The same holds true
for the 'unbind blk' command.

Close the file descriptor when unbinding the host block device.

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include  at all, so
remove that include.

dm: treewide: Rename dev_get_platdata() to dev_get_plat()

dm: treewide: Rename 'platdata' variables to just 'plat'

2020-12-13T23:51:08+00:00

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).

Rename some of the latter variables to end with 'plat' for consistency.
