8 years agodm: usb: Unbind old block devices when shutting down USB
Simon Glass [Sun, 13 Mar 2016 14:22:33 +0000 (08:22 -0600)]
dm: usb: Unbind old block devices when shutting down USB

When 'usb start' is used, block devices are created for any USB flash sticks
and disks, etc. When 'usb stop' is used, these block devices are currently
not removed.

We don't want old block devices hanging around since they can still be
visible to U-Boot. Therefore, when USB is shut down, remove and unbind all
the block devices created by the USB subsystem.

Possibly we should unbind all devices which don't cause problems by being
unbound. Most likely we can remove everything except USB controllers, hubs
and emulators. We can consider that later.

Sometimes it is useful to jump into U-Boot directly from coreboot or UEFI
without any 16-bit init. This can help during development by allowing U-Boot
to avoid doing all the init required by the platform.

U-Boot expects its GDT to be set up correctly by its 16-bit code. If
coreboot doesn't do this (because it hasn't run the payload setup code yet)
then this won't happen.

In this case we cannot rely on the GDT settings. U-Boot will hang or crash
if these are wrong. Provide a development-only option to set up the GDT

8 years agox86: Add an ICH6 pin configuration driver
Simon Glass [Sat, 12 Mar 2016 05:07:13 +0000 (22:07 -0700)]
x86: Add an ICH6 pin configuration driver

Add a driver which sets up the pin configuration on x86 devices with an ICH6
(or later) Platform Controller Hub.

The driver is not in the pinctrl uclass due to some oddities of the way x86
devices work:

- The GPIO controller is not present in I/O space until it is set up
- This is done by writing a register in the PCH
- The PCH has a driver which itself uses PCI, another driver
- The pinctrl uclass requires that a pinctrl device be available before any
other device can be probed

It would be possible to work around the limitations by:
- Hard-coding the GPIO address rather than reading it from the PCH
- Using special x86 PCI access to set the GPIO address in the PCH

However it is not clear that this is better, since the pin configuration
driver does not actually provide normal pin configuration services - it
simply sets up all the pins statically when probed. While this remains the
case, it seems better to use a syscon uclass instead. This can be probed
whenever it is needed, without any limitations.

Also add an 'invert' property to support inverting the input.

8 years agox86: Support booting SeaBIOS

x86: Support booting SeaBIOS

SeaBIOS is an open source implementation of a 16-bit x86 BIOS.
It can run in an emulator or natively on x86 hardware with the
use of coreboot. With SeaBIOS's help, we can boot some OSes
that require 16-bit BIOS services like Windows/DOS.

As U-Boot, we have to manually create a table where SeaBIOS gets
system information (eg: E820) from. The table unfortunately has
to follow the coreboot table format as SeaBIOS currently supports
booting as a coreboot payload.
