global: Convert simple_strtoul() with hex to hextoul()

2021-08-02T17:32:14+00:00

It is a pain to have to specify the value 16 in each call. Add a new
hextoul() function and update the code to use it.

Add a proper comment to simple_strtoul() while we are here.

image: Adjust the workings of fit_check_format()

2021-02-16T03:31:52+00:00

At present this function does not accept a size for the FIT. This means
that it must be read from the FIT itself, introducing potential security
risk. Update the function to include a size parameter, which can be
invalid, in which case fit_check_format() calculates it.

For now no callers pass the size, but this can be updated later.

Also adjust the return value to an error code so that all the different
types of problems can be distinguished by the user.

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include  at all, so
remove that include.

splash: Load internal and external data from FIT

2019-05-20T09:56:41+00:00

The FIT image could contain the splash data in 3 different structure:
- The splash data is embedded in FIT image (internal)
  In this case, the property 'data' presents in FIT image header. And
  internal information 'start' and 'end' represent the location and
  size of splash data inside of FIT image.
- The splash data is external with absolute position in FIT image
  This case is made by 'mkimage -p [pos]'. The splash data is stored
  at the absolute position. Instead the property 'data', the properties
  'data-position' and 'data-size' are used to specify the location and
  size of the splash data.
- the splash data is external with relative offset in FIT image
  This case is made by 'mkimage -E'. The splash data is placed after
  the FIT image header with 4 byte alignment. Instead the property
  'data', the properties 'data-offset' and 'data-size' are used to
  specify the location and size of the splash data.

Currently, the splash only support to load external data with relative
offset from FIT image. This commit make it possible to load the splash
data embedded in FIT image or the external data with absolute position

This inspiration comes from Simon Glass , see

splash: Use splashfile instead of location->name

2019-05-20T09:55:42+00:00

The splash image could be loaded from different sources (e.g. sf, mmc)
with different formats (e.g. raw, file-system). These sources are
structured by a board dependent object 'splash_location'. To decide
where is the splash image loaded, following environment variables are
used to select the splash source and file:
- 'splashsource' is used to select the splash source by setting its
  value to specified name of splash location.
- 'splashfile' specify the name of splash image file

But, when loads the splash image from FIT, the name of splash image
within FIT is specified by splash location name. Due to the splash
location name is already used for the splash source, its name may
conflicts with the name of splash image.

To solve the conflict, the environment variable 'splashfile' is used
to specify the splash image in FIT, and keeps the splash location
name for the splash source.
