spl: fix build failure with !CONFIG_SPL_PCI_SUPPORT Building U-Boot with CONFIG_PCI and CONFIG_DM_PCI enabled, but CONFIG_SPL_PCI_SUPPORT disabled, results in following linker error: lib/built-in.o: In function `fdtdec_get_pci_bar32': lib/fdtdec.c:305: undefined reference to `dm_pci_read_bar32' fdtdec.c:305:(.text.fdtdec_get_pci_bar32+0x24): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dm_pci_read_bar32' This is because reference to dm_pci_read_bar32() remains in lib/fdtdec.c while SPL build does not descend into drivers/pci directory in drivers/Makefile if CONFIG_SPL_PCI_SUPPORT is not enabled. Fix this by applying appropriate #define guards in lib/fdtdec.c. It looks like ns16550.c has the same problem, so fixed that too. To simplify this, CONFIG_SPL_PCI_SUPPORT is renamed to CONFIG_SPL_PCI (enables use of CONFIG_IS_ENABLED() macro).

While loading from serial is slow it can be a useful backup when

means of transmitting U-Boot over a serial line for using in TPL,
with a checksum to ensure correctness.

spl: at91: add support for SPL_AT91_MCK_BYPASS By default the configuration of the PMC is to have an external crystal connected that requires driving on both XIN and XOUT pins. The bypass configuration means that only XIN will be used, the SoC will not do any driving, and the XIN needs to be provided with a proper signal. This is the MOSCXTBY bit in the PMC main clock generator register. The SPL needs to properly initialize the PMC registers before switching to external clock signal and raising the clock to the cruise speed. Also created Kconfig for this specific configuration. By default this is disabled. Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com>

Use external 8 to 24 Mhz clock signal as source of main clock instead
of an external crystal oscillator.
This option disables the internal driving on the XOUT pin.
The external source has to provide a stable clock on the XIN pin.
If this option is disabled, the SoC expects a crystal oscillator
that needs driving on both XIN and XOUT lines.
