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.

dm: Rename U_BOOT_DEVICE() to U_BOOT_DRVINFO()

2021-01-05T19:26:35+00:00

The current macro is a misnomer since it does not declare a device
directly. Instead, it declares driver_info record which U-Boot uses at
runtime to create a device.

The distinction seems somewhat minor most of the time, but is becomes
quite confusing when we actually want to declare a device, with
of-platdata. We are left trying to distinguish between a device which
isn't actually device, and a device that is (perhaps an 'instance'?)

It seems better to rename this macro to describe what it actually is. The
macros is not widely used, since boards should use devicetree to declare
devices.

Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is
declaring a new driver_info record, not a device.

dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25+00:00

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

crypto/fsl: add RNG support

2020-07-27T08:46:29+00:00

Register the random number generator with the rng subsystem in u-boot.
This way it can be used by EFI as well as for the 'rng' command.

crypto/fsl: instantiate the RNG with prediciton resistance

2020-07-27T08:46:29+00:00

If it is already instantiated tear it down first and then reinstanciate
it again with prediction resistance.

crypto/fsl: don't regenerate secure keys

2020-07-27T08:46:29+00:00

The secure keys (TDKEK, JDKEK, TDSK) can only be generated once after a
POR. Otherwise the RNG4 will throw an error.
