db41d65a97 common: Move hang() to the same header as panic()
At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.

73c6cd6c0b x86: Quieten TPL's jump_to_image_no_args()
We already a message indicating that U-Boot is about to jump to SPL, so
make this one a debug() to reduce code size.

09455d3a8f x86: Don't print CPU info in TPL
We don't need to do this and it is done (in more detail) in U-Boot proper.
Drop this to save code space.

0e72ac7150 x86: Move CPU init to before spl_init()
At present we call spl_init() before identifying the CPU. This is not a
good idea - e.g. if bootstage is enabled then it will try to set up the
timer which works better if the CPU is identified.

Put explicit code at each entry pointer to identify the CPU.

0ced70a0bb x86: tpl: Add a fake PCI bus
In TPL we try to minimise code size so do not include the PCI subsystem.
We can use fixed BARs and drivers can directly program the devices that
they need.

However we do need to bind the devices on the PCI bus and without PCI this
does not ordinarily happen. As a work-around, define a fake PCI bus which
does this binding, but no other PCI operations. This is a convenient way
to ensure that we can use the same device tree for TPL, SPL and U-Boot
proper:

   TPL    - CONFIG_TPL_PCI is not set (no auto-config, fake PCI bus)
   SPL    - CONFIG_SPL_PCI is set (no auto-config but with real PCI bus)
   U-Boot - CONFIG_PCI is set (full auto-config after relocation)

3d95688c85 x86: Panic when SPL or TPL fail
At present when these fail to boot there is no message, just a hang. Add a
panic so it is obvious that something when wrong.

daade119aa x86: spl: Reduce priority of the basic SPL image loader
This image loader works on systems where the flash is directly mapped to
the last part of the 32-bit address space. On recent Intel systems (such
as apollolake) this is not the case.

Reduce the priority of this loader so that another one can override it.

While we are here, rename the loader to BOOT_DEVICE_SPI_MMAP since
BOOT_DEVICE_BOARD is not very descriptive.

14dd93beb7 x86: spl: Use hang() instead of a while() loop
Use the standard hang() function when booting fails since this implements
the defined U-Boot behaviour for this situation.

7c03caf6fa x86: Add a simple TPL implementation
Add the required CPU code so that TPL builds correctly. Also update the
SPL code to deal with being booted from TPL.
