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
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.

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.

spl: fix binman_sym output check

2018-04-03T10:10:24+00:00

A previous commit introduced the use of binman in the SPL.

After the binman_sym call over the 'pos' symbol, the output value is
checked against BINMAN_SYM_MISSING (-1UL). According to the
documentation (tools/binman/README), when it comes to the 'pos'
attribute:

pos:
	This sets the position of an entry within the image. The first
	byte of the image is normally at position 0. If 'pos' is not
	provided, binman sets it to the end of the previous region, or
	the start of the image's entry area (normally 0) if there is no
	previous region.

So instead of checking if the return value is BINMAN_SYM_MISSING, we
should also check if the value is not null.

The failure happens when using both the SPL file and the U-Boot file
independently instead of the concatenated file (SPL + padding + U-Boot).
This is because the U-Boot binary file alone does not have the U-Boot
header while it is present in the concatenation file. Not having the
header forces the SPL to discover where it should load U-Boot. The
binman_sym call is supposed to do that but fails. Because of the wrong
check, the destination address was set to 0 while it should have been
somewhere in RAM. This, obviously, stalls the board.

spl: include timezone in banner

Include the timezone in the SPL banner so the timestamp matches with

Selecting this option will reduce SPL boot time by approx. 6 ms
(e. g. with 70 bytes long banner string at 115200 baud).

binman: Add binman symbol support to SPL

2017-12-13T02:53:45+00:00

Allow SPL to access binman symbols and use this to get the address of
U-Boot. This falls back to CONFIG_SYS_TEXT_BASE if the binman symbol
is not available.

spl: atf: introduce spl_invoke_atf and make bl31_entry private

2017-11-25T23:39:07+00:00

This adds a new interface spl_invoke_atf() that takes a spl_image_info
argument and then derives the necessary parameters for the ATF entry.
Based on the additional information recorded (into /fit-images) from
the FIT loadables, we can now easily locate the next boot stage.

We now pass a pointer to a FDT as the platform-specific parameter
pointer to ATF (so we don't run into the future headache of every
board/platform defining their own proprietary tag-structure), as
FDT access is already available in ATF.

With the necessary infrastructure in place, we can now update the
support for the ARM Trusted Firmware to dispatch into the
spl_invoke_atf function only if a IH_OS_ARM_TRUSTED_FIRMWARE image is
loaded.

spl: fix assignment of board info to global data

2017-10-09T15:48:44+00:00

Commit 15eb1d43bf47 ("spl: reorder the assignment of board info to
global data") intended to move assignment of board info earlier,
into board_init_r(). However, function preload_console_init() is
called either from spl_board_init() or from board_init_f(). For the
latter case, the board info assignment is much earlier than proposed
board_init_r(). Create a new function to fill gd->bd and call this
function when needed.
