U-Boot can be built as a 32-bit binary which runs in 32-bit mode
|
|
|
|
|
even on 64-bit machines. In this case SPL is not used, and U-Boot
|
|
|
|
|
runs directly from the reset vector (via 16-bit start-up).
|
|
|
|
|
|
|
|
|
|
Alternatively it can be run as a 64-bit binary, thus requiring a
|
|
|
|
|
64-bit machine. In this case SPL runs in 32-bit mode (via 16-bit
|
|
|
|
|
start-up) then jumps to U-Boot in 64-bit mode.
|
|
|
|
|
|
|
|
|
|
For now, 32-bit mode is recommended, as 64-bit is still
|
|
|
|
|
experimental and is missing a lot of features.

Build U-Boot as a 32-bit binary with no SPL. This is the currently

|
|
|
|
supported normal setup. U-Boot will stay in 32-bit mode even on
|
|
|
|
|
64-bit machines. When booting a 64-bit kernel, U-Boot will switch
|
|
|
|
|
to 64-bit just before starting the kernel. Only the bottom 4GB of
|
|

memory can be accessed through normal means, although

arch_phys_memset() can be used for basic access to other memory.

U-Boot can support up to 254 IRQ slot info in the PIRQ routing table
|
|
|
|
|
which in turns forms a table of exact 4KiB. The default value 128
|
|

|
should be enough for most boards. If this does not fit your board,
|
|
|
|
|
change it according to your needs.

configuration space through I/O access, but memory access is more

convenient. Using this, PCI can be scanned and configured. This

assigned to PCI devices - i.e. the memory and prefetch regions, as

passed to pci_set_region().

SeaBIOS is an open source implementation of a 16-bit X86 BIOS.
|

|
|
|
It can run in an emulator or natively on X86 hardware with the use
|
|
|
|
|
of coreboot/U-Boot. By turning on this option, U-Boot prepares
|
|
|
|

all the configuration tables that are necessary to boot SeaBIOS.

SeaBIOS itself resides in E seg and F seg, where U-Boot puts all
|
|
|
|
|
configuration tables like PIRQ/MP/ACPI. To avoid conflicts, U-Boot
|
|
|
|
|
puts a copy of configuration tables in high memory region which
|
|
|
|
|
is reserved on the stack before relocation. The region size is
|
|
|
|
|
determined by this option.
|
|
|
|
|
|
|
|
|
|
Increse it if the default size does not fit the board's needs.
|
|
|
|
|
This is most likely due to a large ACPI DSDT table is used.
