6912f2a8ae watchdog: omap_wdt: Disable DM watchdog support in SPL
This patch disables DM watchdog support for SPL builds and uses
the legacy omap watchdog driver on TI AM335x chipsets.

The following build error is reported if DM watchdog support was
enabled in SPL:

  CC      spl/drivers/usb/gadget/rndis.o
  LD      spl/drivers/usb/gadget/built-in.o
  LD      spl/drivers/usb/musb-new/built-in.o
  LD      spl/drivers/built-in.o
  LD      spl/u-boot-spl
arm-linux-ld.bfd: u-boot-spl section .u_boot_list will not fit in region .sram
arm-linux-ld.bfd: region .sram overflowed by 440 bytes
make[1]: *** [spl/u-boot-spl] Error 1
make: *** [spl/u-boot-spl] Error 2

Adjusted WATCHDOG_RESET macro accordingly. Earlier it was pointing
to hw_watchdog_reset. Since CONFIG_WATCHDOG replaces CONFIG_HW_WATCHDOG,
now WATCHDOG_RESET macro points to watchdog_reset. This watchdog_reset
is not defined anywhere for am33xx/omap2 and needs to be defined. Fixed
this by simply calling hw_watchdog_reset in watchdog_reset.

Built and tested on AM335x device (BeagleboneBlack), compile tested for
all other AM33xx/omap2 based boards.

7659ea32a6 watchdog: omap_wdt: Convert watchdog driver to use DT and DM
This patch adds device tree and driver model watchdog support,
converts the legacy omap watchdog driver to driver model for
TI AM335x chipsets. The following compile warning is removed:

===================== WARNING ======================
This board does not use CONFIG_WDT (DM watchdog support).
Please update the board to use CONFIG_WDT before the
v2019.10 release.
Failure to update by the deadline may result in board removal.
See doc/driver-model/MIGRATION.txt for more info.
====================================================

CONFIG_HW_WATCHDOG is no more a default option for AM33XX devices
after DT/DM conversion, adjusted kconfig accordingly.

DM watchdog support is enabled by default in SPL. The SPL image
doesn't fit into SRAM because of size constraints and build breaks
with an overflow. For this reason DM watchdog support should be
disabled in SPL, driver code should be adjusted accordingly to serve
this purpose.
Built and tested on AM335x device (BeagleboneBlack), compile tested
for all other AM33xx based boards.

Please further note that with this change the USB hub on the Apalis
Evaluation board is kept in reset in U-Boot and therefore none of its
ports are operational in U-Boot.

indented, as if it's some kind of generic MMC configuration option.

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

This means we end up with these files when building x86 boards:

   board/dfi/dfi-bt700/dsdt.aml
   board/dfi/dfi-bt700/dsdt.asl.tmp

Update the code to put temporary files in the target directory instead.

The iasl tool is quite confusing since it generates files with different
extensions and does not allow these to be individually specified. Add some
documentation to help with this.

e3be52ceac x86: acpi: Enable ACPI companion for Intel iDMA 32-bit
ACPI has a capability to specify DMA parameters for DMA channel consumers.
To enable this for Intel Edison, describe GP DMA device in ACPI table
in order to get an ACPI handle to it in OS.

This works in conjunction with CSRT, which must be in align with DSDT.

provides acpi_fill_csrt() function, it will be used to populate the table.

68d70a1cf6 x86: qemu: Fix non-working ramboot and nfsboot environment variables
With qemu-x86 starting to use config_distro_bootcmd, the pre-defined
ramboot and nfsboot commands do not work any more. This is caused by
undefined environment variable 'ramdiskaddr' that was previously set
in CONFIG_EXTRA_ENV_SETTINGS but later CONFIG_EXTRA_ENV_SETTINGS was
redefined for distro boot.

Update the x86 generic CONFIG_EXTRA_ENV_SETTINGS to consider distro
boot, and remove the one in qemu-x86.h.

00f237e226 qemu-x86: Use config_distro_bootcmd
Converts qemu x86 machines to boot using distro_config. The intent is to
allow u-boot in qemu to be maximally compatible with many boot methods
without having to change the config. Previously, u-boot would only boot
in a very limited set of circumstances where there was a /boot/vmlinuz
on scsi 0:3 with no ramdisk.
