commit c3c016cf "sf: Add SPI NOR protection mechanism" introduced
flash_lock()/flash_unlock()/flash_is_locked() methods for SPI flash,
but not every flash driver supplies these. We should test these
methods against NULL before actually calling them.

According to Atom E6xx datasheet, setting VGA Disable (bit17)
of Graphics Controller register (offset 0x50) prevents IGD
(D2:F0) from reporting itself as a VGA display controller
class in the PCI configuration space, and should also prevent
it from responding to VGA legacy memory range and I/O addresses.

However test result shows that with just VGA Disable bit set and
a PCIe graphics card connected to one of the PCIe controllers on
the E6xx, accessing the VGA legacy space still causes system hang.
After a number of attempts, it turns out besides VGA Disable bit,
the SDVO (D3:F0) device should be disabled to make it work.

To simplify, use the Function Disable register (offset 0xc4)
to disable both IGD (D2:F0) and SDVO (D3:F0) devices. Now these
two devices will be completely disabled (invisible in the PCI
configuration space) unless a system reset is performed.

sparc: Updates to SPARC architecture in preperation for generic board

This patch series is a backlog of preparation work for upcomming
generic board changes.

I first want to get these reviewed and submitted to mainline before
sending out more patches.
END

Prior to commit 5ba534d2 ("arm: Switch 32-bit ARM to using generic
global_data setup") we used to have assembly code that configured the
malloc_base address.

Since this commit we use the board_init_f_mem() function in C to setup
malloc_base address.

In board_init_f_mem() there was a deliberate choice to support only
early malloc() or full malloc() in SPL, but not both.

Adapt this logic to allow both to be used, one after the other, in SPL.

This issue has been observed in a Congatec board, where we need to
retrieve the manufacturing information from the SPI NOR (the SPI API
calls malloc) prior to configuring the DRAM. In this case as malloc_base
was not configured we always see malloc to fail.

With this change we are able to use malloc in SPL prior to DRAM gets
initialized.

Also update the CONFIG_SYS_SPL_MALLOC_START entry in the README file.
