command called 'uga' to show whether UGA is implemented by the
firmware and what the settings are. It also includes filling
the efi_fb structure from the UGA information when GOP isn't
implemented by the firmware.
Since UGA does not provide information about the stride, we
set the stride to the horizontal resolution. This is likely
not correct and we should determine the stride by trial and
error. For now, this should show something on the console
rather than nothing.

command has the following sub-commands:
list - list all possible modes (paged)
get - return the current mode
set <mode> - set the current mode to <mode>
Go ahead and defined -D_STANDALONE for all targets (only strictly
needed for some architecture, but harmless on those it isn't required
for). Also add -msoft-float to all architectures uniformly rather
that higgley piggley like it is today.

"fdt_file" and "fdtfile" U-Boot variables. Add one more check for
"fdt_file" loader(8) variable.
loader(8) variable takes precedence over u-boot env one
like RPI-B and RPI-2.
Description of problem:
USB transfers can process data in their callbacks sometimes causing
unacceptable latency for other USB transfers. Separate BULK completion
callbacks from CONTROL, INTERRUPT and ISOCHRONOUS callbacks, and give
BULK completion callbacks lesser execution priority than the
others. This way USB audio won't be interfered by heavy USB ethernet
usage for example.
Further serve USB transfer completion in a round robin fashion,
instead of only serving the most CPU hungry. This has been done by
adding a third flag to USB transfer queue structure which keeps track
of looping callbacks. The "command" callback function then decides
what to do when looping.

The UEFI loader on the 10.1 release install disk (disc1) modifies an
existing EFI_DEVICE_PATH_PROTOCOL instance in an apparent attempt to
truncate the device path. In doing so it creates an invalid device
path.
Perform the equivalent action without modification of structures

The Allwinner SoC has an AHCI device on its internal main bus rather
than the PCI bus. This SoC is somewhat underdocumented, and its SATA
controller is no exception. The methods to support this chip were
harvested from the Linux Allwinner SDK, and then constants invented to
describe what's going on based on low-level constants contained in the
SATA standard and guess work.
This SoC requires a specific AHCI channel setup in order to start the
operations on the channel properly.
Clock setup and AHCI channel setup idea came from NetBSD.
Tested on Cubieboard 2 and Banana pi (and attachment on Cubieboard by

The net result is that any unfortunate user of the loader's ub_env_enum()
function hitting this condition would be trapped in the infinite loop, as
the main use pattern of ub_env_enum() is basically the following:
while ((env = ub_env_enum(env)) != NULL) { DO STUFF }
Which would stuck forever with the last element.
fails to properly consider memory regions when the loader is
located below of those regions or engulfs their lower limit. This
results in "not enough RAM to load kernel" panic, which is totally
bogus. On top of that, there are some variables that can be left
unitialized in those cases, which might cause it fail with memory
access violation instead of panic while trying to load kernel to
a wrong or non-existing address of memory.
Augment the code to properly deal with the loader being below or
at the lower bound of the memory region in question. Also, don't
leave ununitialized variables behind.

- Better error handling;
- Clock is derived from PLL6 (obtained from netbsd);
- No more unnecessary busy loops on interrupt handler;
- style(9) fixes and code cleanup.
