SPDX: Convert all of our multiple license tags to Linux Kernel style

2018-05-07T14:24:31+00:00

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 multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document.  Note that parenthesis are
allowed so when they were used before we continue to use them.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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

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.

stdio_names: Ensure MAX_NAMES is defined before use, don't use 3 directly

2018-05-06T17:35:16+00:00

With tighter build flags the fact that  doesn't have a
reference back to MAX_NAMES causes an error.  Include  here and
then in common/console.c use MAX_NAMES rather than 3 when working with
stdio_names.

spl: Split sprintf, strto* from SPL serial in Kconfig

2018-04-28T22:32:23+00:00

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.

Split printf, sprintf and strto into their own entries and then select
all of them if SERIAL_SUPPORT is enabled to match the current behaviour.

Include panic.o unconditionally as it can be called from anywhere which
uses BUG_ON().

spl: Add dependency on serial to Ymodem

Building with Ymodem support requires serial in SPL/TPL, add that
dependency here.

spl: ti: Avoid preloader_console_init if !CONFIG_SPL_SERIAL_SUPPORT

2018-04-28T22:32:22+00:00

If CONFIG_SPL_SERIAL_SUPPORT is disabled then the build fails because
serial_init is undefined. Guard preloader_console_init() appropriately
to fix this.

log: CONFIG_LOG should select CONFIG_DM

2018-04-28T14:42:35+00:00

Compling with CONFIG_LOG and without CONFIG_DM results in

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

2018-04-27T18:54:48+00:00

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

Convert CONFIG_SPI to Kconfig

2018-04-27T18:54:11+00:00

This converts the following to Kconfig:
   CONFIG_SPI

This partly involves updating code that assumes that CONFIG_SPI implies
things that are specific to the MPC8xx SPI driver.  For now, just update
the CONFIG tests.  This also involves reworking the default for
CONFIG_SYS_DEF_EEPROM_ADDR so that we don't set it when we cannot make a
reasonable default, as it does not cause any compile failures.

bootm: Align cache flush begin address

2018-04-17T21:45:08+00:00

commit b4d956f6bc0f ("bootm: Align cache flush end address correctly")
aligns the end address of the cache flush operation to a cache-line size to
ensure lower-layers in the code accept the range provided and flush.

A similar action should be taken for the begin address of a cache flush
operation. The load address may not be aligned to a cache-line boundary, so
ensure the passed address is aligned.
