8f10b5c656 spl: Print from which mmc slot spl is trying to boot
On some sunxi boards (and presumably also non sunxi boards) u-boot can
be either loaded from a sdcard in a micro-sd slot, or from eMMC.

Print which MMC spl tries to boot from, to help debugging.

c998da0d67 usb: Change power-on / scanning timeout handling
This patch changes the USB port scanning procedure and timeout
handling in the following ways:

a)
The power-on delay in usb_hub_power_on() is now reduced to a value of
max(100ms, "hub->desc.bPwrOn2PwrGood * 2"). The code does not wait
using mdelay, instead usb_hub_power_on() will wait before querying
the device in the scanning loop later. The total timeout for this
hub, which is 1 second + "hub->desc.bPwrOn2PwrGood * 2" is calculated
and will be used in the following per-port scanning loop as the timeout
to detect active USB devices on this hub.

b)
Don't delay the minimum delay (for power to stabilize) in
usb_hub_power_on(). Instead skip querying these devices in the scannig
loop until the delay time is reached.

c)
The ports are now scanned in a quasi parallel way. The current code did
wait for each (unconnected) port to reach its timeout and only then
continue with the next port. This patch now changes this to scan all
ports of all USB hubs quasi simultaneously. For this, all ports are added
to a scanning list. This list is scanned until all ports are ready
by either a) reaching the connection timeout (calculated earlier), or
by b) detecting a USB device. This results in a faster USB scan time as
the recursive scanning of USB hubs connected to the hub that's currently
being scanned will start earlier.

One small functional change to the original code is, that ports with
overcurrent detection will now get rescanned multiple times
(PORT_OVERCURRENT_MAX_SCAN_COUNT).

Without this patch:
starting USB...
USB0:   USB EHCI 1.00
scanning bus 0 for devices... 9 USB Device(s) found

time: 20.163 seconds

With this patch:
starting USB...
USB0:   USB EHCI 1.00
scanning bus 0 for devices... 9 USB Device(s) found

time: 1.822 seconds

So ~18.3 seconds of USB scanning time reduction.

3ed9eb93c2 usb: Don't reset the USB hub a 2nd time
Debugging has shown, that all USB hubs are being reset twice while
USB scanning. This introduces additional delays and makes USB scanning
even more slow. Testing has shown that this 2nd USB hub reset doesn't
seem to be necessary.

This patch now removes this 2nd USB hub reset. Resulting in faster USB
scan time. Here the current numbers:

Without this patch:
=> time usb start
starting USB...
USB0:   USB EHCI 1.00
scanning bus 0 for devices... 9 USB Device(s) found

time: 24.003 seconds

With this patch:
=> time usb start
starting USB...
USB0:   USB EHCI 1.00
scanning bus 0 for devices... 9 USB Device(s) found

time: 20.392 seconds

So ~3.6 seconds of USB scanning time reduction.

f7f601002d usb: legacy_hub_port_reset(): Speedup hub reset handling
Start with a short USB hub reset delay of 20ms. This can be enough for
some configurations.

The 2nd delay at the end of the loop is completely removed. Since the
delay hasn't been long enough, a longer delay time of 200ms is assigned
and will be used in the next loop round.

This hub reset handling is also used in the v4.4 Linux USB driver,
hub_port_reset().

e4d6ab0c2c x86: Allow use of serial soon after relocation
At present on x86 machines with use cache-as-RAM, the memory goes away just
before board_init_r() is called. This means that serial drivers are
no-longer unavailable, until initr_dm() it called, etc.

Any attempt to use printf() within this period will cause a hang.

To fix this, mark the serial devices as 'unavailable' when it is no-longer
available. Bring it back when serial_initialize() is called. This means that
the debug UART will be used instead for this period.

5d00995c36 efi_loader: Implement memory allocation and map
The EFI loader needs to maintain views of memory - general system memory
windows as well as used locations inside those and potential runtime service
MMIO windows.

To manage all of these, add a few helpers that maintain an internal
representation of the map the similar to how the EFI API later on reports
it to the application.

For allocations, the scheme is very simple. We basically allow allocations
to replace chunks of previously done maps, so that a new LOADER_DATA
allocation for example can remove a piece of the RAM map. When no specific
address is given, we just take the highest possible address in the lowest
RAM map that fits the allocation size.

50149ea37a efi_loader: Add runtime services
After booting has finished, EFI allows firmware to still interact with the OS
using the "runtime services". These callbacks live in a separate address space,
since they are available long after U-Boot has been overwritten by the OS.

This patch adds enough framework for arbitrary code inside of U-Boot to become
a runtime service with the right section attributes set. For now, we don't make
use of it yet though.

We could maybe in the future map U-boot environment variables to EFI variables
here.

   CONFIG_OF_SYSTEM_SETUP
   CONFIG_FIT_SIGNATURE
   CONFIG_FIT_BEST_MATCH

   CONFIG_OF_STDOUT_VIA_ALIAS
   CONFIG_RSA

Unfortunately the first one is a little complicated. We need to make sure
this option is not enabled in SPL by this change. Also this option is
enabled automatically in the host builds by defining CONFIG_FIT in the
image.h file. To solve this, add a new IMAGE_USE_FIT #define which can

0cb389dd1a image: fix getenv_bootm_size() function again
Commit 9c11135ce0 ("image: fix getenv_bootm_size() function") fixed
the case where "bootm_low" is defined, but "bootm_size" is not.
Instead, it broke the case where neither "bootm_low" nor "bootm_size"
is defined.  Fix this function again.

ee05fedc6c malloc: solve dead code issue in memalign()
The recent change to memalign() caused the allocation failure detection
code to be dead code; the "retry" logic is always activated under the same
condition that the original failure detection code is, and also fully
handles any possible failures. This patch solves the presence of dead
code.

Two alternatives are possible:

a) Delete the now-dead test, and rely on the "retry" path to handle any
allocation problems, as it does.

b) Make the "retry" path fall through to the existing (currently dead)
failure detection code, thus making it not-dead.

(b) was chosen since it reduces the diff between U-Boot's and the upstream
dlmalloc. This should make it marginally easier to import a new version of
dlmalloc in the future.

8e7cba048b common/memsize.c: Simplify RAM size detection
The case of memory of size 0 is not that different from a memory of any other
size, so we remove the duplicate code and treat the small differences when it
is the case.
