da2364cc14 Revert "x86: Convert MMC to driver model"
This reverts commit ddb3ac3c71.

With MMC converted to driver model, SCSI driver is broken due to
zero address access at (ops->read) in block_dread() function.

The fix (SCSI driver converted to DM) is ready in u-boot-dm branch,
but it is too late for this relese to get that in.

0c2b7eef97 x86: Unify reserve_arch() for all x86 boards
Instead of asking each platform to provide reserve_arch(),
supply it in arch/x86/cpu/cpu.c in a unified way.

12d6929e1f dm: x86: Set up interrupt routing from interrupt_init()
At present interrupt routing is set up from arch_misc_init(). We can do it
a little later instead, in interrupt_init().

This removes the manual pirq_init() call. Where the platform does not have
an interrupt router defined in its device tree, no error is generated. Some
platforms do not have this.

Drop pirq_init() since it is no-longer used.

4abe8e40a7 dm: Convert PCI MMC over to use DM PCI API
At present pci_mmc_init() does not correctly use the PCI function since the
list it passes is not terminated. The array size passed to pci_mmc_init() is
actually not used correctly. Fix this and adjust the pci_mmc_init() to scan
all available MMC devices.

Adjust this code to use the new driver model PCI API.

This should move over to the new MMC uclass at some point.

74e56d1953 x86: baytrail: Issue full system reset in reset_cpu()
With MRC cache enabled, when typing 'reset' in the U-Boot shell,
BayTrail FSP initialization hangs at "Configuring Memory Start":

Changing reset_cpu() to do a full system reset fixes this issue.

fa6af7b4e0 x86: baytrail: Remove the fsp_init_phase_pci() call
It turns out that calling fsp_init_phase_pci() in arch_misc_init()
is subject to break pci device drivers as with driver model, when
the bus enumeration happens is not deterministic.

3a1a18ff18 x86: Add support for Intel Minnowboard Max
This is a relatively low-cost x86 board in a small form factor. The main
peripherals are uSD, USB, HDMI, Ethernet and SATA. It uses an Atom 3800
series CPU. So far only the dual core 2GB variant is supported.

This uses the existing FSP support. Binary blobs are required to make this
board work. The microcode update is included as a patch (all 3000 lines of
it).
