bcd4e6f3bd x86: Change how selection of ROMs works
Most x86 boards build a u-boot.rom which is programmed into SPI flash. But
this is not unique to x86. For example some rockchip boards can also boot
from SPI flash.

Also, at least on x86, binary blobs are sadly quite common. It is not
possible to build a functional image without them, and U-Boot needs to
know this at build time.

Introduce a new CONFIG_HAS_ROM option which selects whether u-boot.rom is
built and a new CONFIG_ROM_NEEDS_BLOBS option to indicate whether binary
blobs are also needed. If they are not needed, it is safe to build the ROM
always. Otherwise we still require the BUILD_ROM environment variable.

For now this affects only x86, but future patches will enable this for
rockchip too.

b75d8dc564 treewide: convert bd_t to struct bd_info by coccinelle
The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

  It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

  void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

  #include <asm/u-boot.h>
  void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

  struct bd_info;
  void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

  <smpl>
  @@
  typedef bd_t;
  @@
  -bd_t
  +struct bd_info
  </smpl>

b95611f67e x86: apl: Fix save/restore of ITSS priorities
The FSP-S changes the ITSS priorities. The code that tries to save it
before running FSP-S and restore it afterwards does not work as U-Boot
relocates in between the save and restore. This means that the driver
data saved before relocation is lost and the new driver just sees zeroes.

Fix this by allocating space in the relocated memory for the ITSS data.
Save it there and access it from the driver after relocation.

This fixes interrupt handling on coral.

Also drop the log_msg_ret() in irq_first_device_type() since this function
can be called speculatively in places where we are not sure if there is
an interrupt controller of that type. The resulting log errors are
confusing when there is no error.

d7413deadd x86: spl: Print the error on SPL failure
The error code is often useful to figure out what is going on. Printing it
does not increase code size much, so print out the error and then hang.

8e2922e357 x86: spi: Add a way to access the SPI mapping via registers
At present the PCI BDF (bus/device/function) is needed to access the SPI
mapping, since the registers are at BAR0. This doesn't work when PCI
auto-config has not been done yet, since BARs are unassigned.

Add another way to find the mapping, using the MMIO base, if the caller
knows this.

Also add a missing function comment.

0621b5e1ee cbfs: Don't require the CBFS size with cbfs_init_mem()
The size is not actually used since it is present in the header. Drop this
parameter. Also tidy up error handling while we are here.
