bdeb2bccbf x86: Rename turbo ratio MSR to MSR_TURBO_RATIO_LIMIT
This MSR number is used on most modern Intel processors, so drop the
confusing NHM prefix (which might mean Nehalem).

6172e94c3c x86: Change condition for using CAR
At present we assume that CAR (Cache-as-RAM) is used if HOBs (Hand-off
blocks) are not, since HOBs typically indicate that an FSP is in use, and
FSPs handle the CAR init.

However this is a bit indirect, and for FSP2 machines which use their own
CAR implementation (such as apollolake) but use the FSP for other
functions, the logic is wrong.

To fix this, add a dedicated Kconfig option to indicate when CAR is used.

c3863eadbc x86: fsp: Save usable RAM and hob_list in the handoff area
The useable RAM is calculated when the RAM is inited. Save this value so
that it can be easily used in U-Boot proper.

Also save a pointer to the hob list so that it is accessible (before
relocation only) in U-Boot proper. This avoids having to scan it in SPL,
for everything U-Boot proper might need later.

544293f878 x86: Add new slimbootloader CPU type
This slimbootloader CPU type is to enable U-Boot as a payload which
runs on top of Slim Bootloader (https://github.com/slimbootloader).
The Slim Bootloader is designed with multi-stage architecture for
the execution from reset vector to OS booting, and supports QEMU,
Apollolake, Whiskeylake and Coffeelake platforms consuming Intel
FSP (https://github.com/IntelFsp) for silicon initialization
including CAR and memory initialization.
The Slim Bootloader generates new HOB (Hand Off Block) which are
serial port info, memory map info, performance data info and so on,
and passes it to a Payload. U-Boot as a payload will use these HOB
information for basic initialization such as serial console.

As an initial commit,
- Add CONFIG_SYS_SLIMBOOTLOADER to enable slimbootloader CPU type
- Add new arch/x86/cpu/slimbootloader directory with minimum codes
- Get hob_list pointer from Slim Bootloader

ef329a6a73 sysreset: Remove DM_FLAG_PRE_RELOC flag in various drivers
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
bound before relocation. However due to a bug in the DM core,
the flag only takes effect when devices are statically declared
via U_BOOT_DEVICE(). This bug has been fixed recently by commit
"dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
lists_bind_fdt()", but with the fix, it has a side effect that
all existing drivers that declared DM_FLAG_PRE_RELOC flag will
be bound before relocation now. This may expose potential boot
failure on some boards due to insufficient memory during the
pre-relocation stage.

To mitigate this potential impact, the following changes are
implemented:

- Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
  only supports configuration from device tree (OF_CONTROL)
- Keep DM_FLAG_PRE_RELOC flag in the driver only if the device
  is statically declared via U_BOOT_DEVICE()
- Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
  drivers that support both statically declared devices and
  configuration from device tree

3d2be8003c x86: Fix car_uninit weak symbol definition
Since commit 80df194f01 ("x86: detect unsupported relocation types"),
an error message is seen on QEMU x86 target during boot:

do_elf_reloc_fixups32: unsupported relocation type 0x1 at fff841f0, offset = 0xfff00087
do_elf_reloc_fixups32: unsupported relocation type 0x2 at fff841f8, offset = 0xfff00091

Check offset 0xfff00087 and 0xfff00091 in the u-boot ELF image,

fff00087  000df401 R_386_32          00000000   car_uninit
fff00091  000df402 R_386_PC32        00000000   car_uninit

we see R_386_32 and R_386_PC32 relocation type is generated for
symbol car_uninit, which is declared as a weak symbol in start.S.

However the actual weak symbol implementation ends up nowhere. As
we can see below, it's *UND*.

$ objdump -t u-boot | grep car_uninit
00000000  w      *UND*  00000000 car_uninit

With this fix, it is normal now.

49d5ff439c x86: Fix the mystery of printch() during 64-bit boot
At present in arch_setup_gd() it calls printch(' ') at the end which
has been a mystery for a long time as without such call the 64-bit
U-Boot just does not boot at all.

In fact this is due to the bug that board_init_f() was called with
boot_flags not being set. Hence whatever value being there in the
rdi register becomes the boot_flags if without such magic call.
With a printch(' ') call the rdi register is initialized as 0x20
and this value seems to be sane enough for the whole boot process.

ceeee8f7b5 x86: coreboot: Add generic coreboot payload support
Currently building U-Boot as the coreboot payload requires user
to change the build configuration for a specific board during
menuconfig process. This uses the board's native device tree
to configure the hardware. For example, the device tree provides
PCI address range for the PCI host controller and U-Boot will
re-program all PCI devices' BAR to be within this range. In order
to make sure we don't mess up the hardware, we should guarantee
the range matches what coreboot programs the chipset.

But we really should make the coreboot payload support easier.
Just like EFI payload, we can create a generic coreboot payload
for all x86 boards as well. The payload is configured to include
as many generic drivers as possible. All stuff that touches low
level initialization are not allowed as such is the coreboot's
responsibility. Platform specific drivers (like gpio, spi, etc)
are not included.

7e21fbca26 efi_loader: Rename sections to allow for implicit data
Some times gcc may generate data that is then used within code that may
be part of an efi runtime section. That data could be jump tables,
constants or strings.

In order to make sure we catch these, we need to ensure that gcc emits
them into a section that we can relocate together with all the other
efi runtime bits. This only works if the -ffunction-sections and
-fdata-sections flags are passed and the efi runtime functions are
in a section that starts with ".text".

Up to now we had all efi runtime bits in sections that did not
interfere with the normal section naming scheme, but this forces
us to do so. Hence we need to move the efi_loader text/data/rodata
sections before the global *(.text*) catch-all section.

With this patch in place, we should hopefully have an easier time
to extend the efi runtime functionality in the future.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

4a5a7fcac2 x86: braswell: Fix unexpected crash during Linux kernel boot
It was observed that when booting Linux kernel on Intel Cherry Hill
board, unexpected crash happens quite randomly. Sometimes kernel
just oops, while sometimes kernel throws MCE errors and hangs:

  mce: [Hardware Error]: Machine check events logged
  mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank 4: c400000000010151
  mce: [Hardware Error]: TSC 0 ADDR 130f3f2c0
  mce: [Hardware Error]: PROCESSOR 0:406c3 TIME 1508160686 SOCKET 0 APIC 0 microcode 363

This looks like a hardware error per mcelog. After debugging, it
seems turning off turbo mode on the processor does not expose this
behavior, although U-Boot runs OK with turbo mode on. Suspect it is
related to an errata of Braswell processor.

To fix this, remove the Braswell cpu driver which does the turbo
mode configuration, and switch to use the generic cpu-x86 driver.
Also there is a configuration option in the FSP that turns on the
turbo mode and that has been turned off too.

febdfaabc7 x86: baytrail: Fix unstable ACPI S3 resume
It was observed that when booting a Ubuntu 16.04 kernel, doing ACPI
S3 suspend/resume sometimes causes the Ubuntu kernel hang forever.
The issue is however not reproduced with a kernel built from i386/
x86_64 defconfig configuration.

The unstability is actually caused by unexpected interrupts being
generated during the S3 resume. For some unknown reason, FSP (gold4)
for BayTrail configures the GPIO DFX5 PAD to enable level interrupt
(bit 24 and 25). As this pin keeps generating interrupts during an
S3 resume, and there is no IRQ requester in the kernel to handle it,
the kernel seems to hang and does not continue resuming.

Clear the mysterious interrupt bits for this pin.

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

In case we're building for Intel Edison, we must have 4096 bytes of
zeroes in the beginning on u-boot.bin. This is done in
board/intel/edison/config.mk.

First run sets hardware_id environment variable which is read from
System Controller Unit (SCU).

Serial number (serial# environment variable) is generated based on eMMC
CID.

MAC address on USB network interface is unique to the board but kept the
same all over the time.

Set mac address from U-Boot using following scheme:
	OUI = 02:00:86
	next 3 bytes of MAC address set from eMMC serial number

This allows to have a unique mac address across reboot and flashing.

5ae5aa9310 x86: acpi: Fix Windows S3 resume failure
U-Boot sets up the real mode interrupt handler stubs starting from
address 0x1000. In most cases, the first 640K (0x00000 - 0x9ffff)
system memory is reported as system RAM in E820 table to the OS.
(see install_e820_map() implementation for each platform). So OS
can use these memories whatever it wants.

If U-Boot is in an S3 resume path, care must be taken not to corrupt
these memorie otherwise OS data gets lost. Testing shows that, on
Microsoft Windows 10 on Intel Baytrail its wake up vector happens to
be installed at the same address 0x1000. While on Linux its wake up
vector does not overlap this memory range, but after resume kernel
checks low memory range per config option CONFIG_X86_RESERVE_LOW
which is 64K by default to see whether a memory corruption occurs
during the suspend/resume (it's harmless, but warnings are shown
in the kernel dmesg logs).

We cannot simply mark the these memory as reserved in E820 table
because such configuration makes GRUB complain: unable to allocate
real mode page. Hence we choose to back up these memories to the
place where we reserved on our stack for our S3 resume work.
Before jumping to OS wake up vector, we need restore the original
content there.

3c03f4928e x86: Force 32-bit jumps in interrupt handlers
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.

Since U-Boot only builds for 32-bit on x86, only a 32-bit EFI application

directly using FIT (see doc/uImage.FIT/kernel.its). U-Boot can act as a
payload for both 32-bit and 64-bit EFI.

At present pinctrl driver gets probed in ich6_gpio driver's probe
routine, which has two issues:

 - Pin's PADs only gets configured when GPIO driver is probed, which
   is not done by default. This leaves the board in a partially
   functional state as we must initialize PADs correctly to get
   perepherals fully working.
 - The probe routine of pinctrl driver is called multiple times, as
   normally there are multiple GPIO controllers. It should really
   be called just once.

to cpu_init_r().

911d6f6932 x86: quark: Assign a unique I/O APIC ID
After power-on, both LAPIC and I/O APIC appear with the same APIC ID
zero, which creates an ID conflict. When generating MP table, U-Boot
reports zero as the LAPIC ID in the processor entry, and zero as the
I/O APIC ID in the I/O APIC as well as the I/O interrupt assignment
entries. Such MP table confuses Linux kernel and finally a kernel
panic is seen during boot:

10d569ea1a x86: Fix up PIRQ routing table checksum earlier
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
suggests: copy the table to somewhere else.

e5aa8a9b15 x86: Support a chained-boot development flow
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
correctly. This is just a hack so you can jump to U-Boot from any stage of
coreboot, not just at the end.

66484f0fc0 x86: tnc: Remove IGD and SDVO devices from driver model
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.
