When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

omap-common cache enabling sequence relies on cpu_init_cp15()
(inside start.S) for enabling I-caches. But cpu_init_cp15()
can be skipped if CONFIG_SKIP_LOWLEVEL_INIT is defined. So
enable I-caches if not enabled already.

The 'SDHCI_QUIRK_NO_HISPD_BIT' is used wrong here. The purpose of this
quirk is to tell the sdhci-driver that the IP-core doesn't have a "high-
speed-enable" bit in its registers.

With this commit we change this to the correct quirk:
SDHCI_QUIRK_BROKEN_HISPD_MODE

Signed-off-by: Hannes Schmelzer <hannes.schmelzer@br-automation.com>

Some IP-core implementations of the SDHCI have different troubles on the
silicon where they are placed.

On ZYNQ platform for example Xilinx doesn't accept the hold timing of an
eMMC chip which operates in High-Speed mode and must be forced to
operate in non high-speed mode. To get rid of this
"SDHCI_QUIRK_BROKEN_HISPD_MODE" is introduced.

For more details about this refer to the Xilinx answer-recor #59999
https://www.xilinx.com/support/answers/59999.html



This commit:
- doesn't set HISPD bit on the host-conroller
- reflects this fact within the host-controller capabilities

Upon this the layer above (mmc-driver) can setup the card correctly.

Otherwise the MMC card will be switched into high-speed mode and causes
possible timing violation on the host-controller side.

The size of 'filebuf' was not increased as more and more bytes are read
from stdin, but 'filebuf' was always reallocated to the same fix size.
This works as long as only less bytes than the initial buffer size come
in, for more input this will segfault. (It actually does, I tested
that.) So for each loop cycle the buffer size has to be increased by the
number of bytes we want to read.

Signed-off-by: Alexander Dahl <ada@thorsis.com>

On success read() returns the number of bytes read or zero for EOF. On
error -1 is returned and errno is set, so the right way to test if read
had failed is to test the return value instead of errno.

Enable uart overrun feature which allows to benefits of uart
FIFO usage.

Previously overrun management was disabled, this has to effect
to bypassed the uart FIFO usage even if FIFO was enabled.
In particular configuration, for example when video console is
enabled, copy/pasting a long command line in console results in
corruption. This is due to the fact that a lot of time is consumed
in flushing the cache during frame buffer update, so uart chars are
not read fast enough.

By using uart FIFO and managing overrun, long command line can by
copy/paste in console without being corrupted.

When SPL serial is disabled, callers who need sprintf or strtoul fail
because their inclusion is guarded by CONFIG_SPL_SERIAL_SUPPORT/
CONFIG_TPL_SERIAL_SUPPORT.

all of them if SERIAL_SUPPORT is enabled to match the current behaviour.
