Depending upon the compiler used, IRQ entries could vary in sizes. With
GCC 5.x, the code generator will use short jumps for some IRQ entries
but near jumps for others. For example, GCC 5.4.0 generates the
following:
$ objdump -d interrupt.o
<snip>
00000207 <irq_18>:
207: 6a 12 push $0x12
209: eb 85 jmp 190 <irq_common_entry>
0000020b <irq_19>:
20b: 6a 13 push $0x13
20d: eb 81 jmp 190 <irq_common_entry>
0000020f <irq_20>:
20f: 6a 14 push $0x14
211: e9 7a ff ff ff jmp 190 <irq_common_entry>
00000216 <irq_21>:
216: 6a 15 push $0x15
218: e9 73 ff ff ff jmp 190 <irq_common_entry>
This causes a problem in cpu_init_interrupts(), because the IDT setup
assumed same sizes for all IRQ entries. GCC 4.x always generated 32-bit
jumps, so this previously was not a problem.
The fix is to force 32-bit near jumps for all entries within the
inline assembly. This works for GCC 5.x, and 4.x was already using
that form of jumping.

Patch queue for efi - 2016-10-19
Highlights this time around:
- Add run time service (power control) support for PSCI (fixed in v3)
- Add efi gop pointer exposure
- SMBIOS support for EFI (on ARM)
- efi pool memory unmap support (needed for 4.8)
- initial x86 efi payload support (fixed up in v2)
- various bug fixes

Add the required pieces to support the EFI loader on x86.
Since U-Boot only builds for 32-bit on x86, only a 32-bit EFI application
is supported. If a 64-bit kernel must be booted, U-Boot supports this
directly using FIT (see doc/uImage.FIT/kernel.its). U-Boot can act as a
payload for both 32-bit and 64-bit EFI.

As of today, the latest version FSP (gold4) for BayTrail misses the

default PAD value for the CD pin sets the pin to work in GPIO mode,
which causes card detect status cannot be reflected by the Present

Add a configuration for this pin in the pinctrl node.
Note I've checked the PAD configuration for all the pins in all the
3 controllers (eMMC/SDIO/SD). Only this SDMMC3_CD_B pin does not get
initialized to correct mode by FSP. With fsp,emmc-boot-mode set to

Per ACPI spec, during ACPI OS initialization, OSPM can determine
that the ACPI hardware registers are owned by SMI (by way of the
SCI_EN bit in the PM1_CNT register), in which case the ACPI OS
issues the ACPI_ENABLE command to the SMI_CMD port. The SCI_EN bit
effectively tracks the ownership of the ACPI hardware registers.
However since U-Boot does not support SMI, we report all 3 fields
in FADT (SMI_CMD, ACPI_ENABLE, ACPI_DISABLE) as zero, by following
the spec who says: these fields are reserved and must be zero on
system that does not support System Management mode.
U-Boot seems to behave in a correct way that the ACPI spec allows,
at least Linux does not complain, but apparently Windows does not
think so. During Windows bring up debugging, it is observed that
even these 3 fields are zero, Windows are still trying to issue SMI
with hardcoded SMI port address and commands, and expecting SCI_EN
to be changed by the firmware. Eventually Windows gives us a BSOD
(Blue Screen of Death) saying ACPI_BIOS_ERROR and refuses to start.
To fix this, turn on the SCI_EN bit by ourselves. With this patch,
now U-Boot can install and boot Windows 8.1/10 successfully with
the help of SeaBIOS using legacy interface (non-UEFI mode).

PIRQ routing table checksum is fixed up in copy_pirq_routing_table(),
which is fine if we only write the configuration table once. But with
the SeaBIOS case, when we write the table for the second time, the
checksum will be fixed up to zero per the checksum algorithm, which
is caused by the checksum field not being zero before fix up, since
the checksum has already been calculated in the first run.
To fix this, move the checksum fixup to create_pirq_routing_table(),
so that copy_pirq_routing_table() only does what its function name

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
correctly. This is just a hack so you can jump to U-Boot from any stage of

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.

The Intel GPIO driver can set up the GPIO pin mapping when the first GPIO
is probed. However, it assumes that the first GPIO to be probed is in the
first GPIO bank. If this is not the case then the init will write to the
wrong registers.
Fix this. Also add a note that this code is deprecated. We should move to
using device tree instead.

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.

Intel IvyBridge FSP seems to be buggy that it does not report memory
used by FSP itself as reserved in the resource descriptor HOB. The
FSP specification does not describe how resource descriptor HOBs are
generated by the FSP to describe what memory regions. It looks newer
FSPs like Queensbay and BayTrail do not have such issue. This causes
U-Boot relocation overwrites the important boot service data which is
used by FSP, and the subsequent call to fsp_notify() will fail.
To resolve this, we find out the lowest memory base address allocated
by FSP for the boot service data when walking through the HOB list in
fsp_get_usable_lowmem_top(). Check whether the memory top address is
below the FSP HOB list, and if not, use the lowest memory base address
allocated by FSP as the memory top address.

With recent DM PCI changes to vesa_fb driver, external graphics
card does not work any more. This is because: after setting the
function disable bit, IGD and SDVO devices will disappear in the
PCI configuration space. This however creates an inconsistent state
from a driver model PCI controller point of view, as these two PCI
devices are still attached to its parent's child device list as
maintained by the driver model. Some driver model PCI APIs like
dm_pci_find_class() used in the vesa_fb driver, are referring to
the list to speed up the finding process instead of re-enumerating
the whole PCI bus, so it gets the stale cached data which is wrong.
To fix this, manually remove these two devices.
