rockchip: rk3399: spl: always report errors triggering a hard stop

The RK3399 SPL has two cases that may end in a hard-stop: if either
the pinctrl can not be initialised or if the DRAM fails to initialise.
Both have previously not triggered an error message unless DEBUG was
defined (i.e. both used debug() to print the error).

This converts both error messages to be printed using pr_err() to
ensure that some output points to the cause of the hard-stop.

ARM: vexpress_*_defconfig: Enable CMD_UBI support

This allow for convenient use of QEMU machine to test loading of UBI
filesystem. There are a couple of changes made together of this which
are required:

 1) The malloc must be at least 512 KiB to allow the use of UBI
    filesystem. We are going to enable it in a next patch.

 2) MTD_DEVICE must be enabled, otherwise we get missing symbols
    during the build

Following configs were change:

 - vexpress_aemv8a_dram_defconfig
 - vexpress_aemv8a_juno_defconfig
 - vexpress_aemv8a_semi_defconfig
 - vexpress_ca15_tc2_defconfig
 - vexpress_ca5x2_defconfig

ARM: meson: Add boot device discovery

The Amlogic Meson SoCs ROM supports a boot over USB with a custom protocol.

When no other boot medium are available (or by forcing the USB mode), the
ROM sets the primary USB port as device mode and waits for a Host to
enumerate.

When enumerated, a custom protocol described at [1] permits writing to
memory and execute some specific FIP init code to run the loaded
Arm Trusted Firmware BL2 and BL3 stages before running the BL33 stage.

In this mode, we can load different binaries that can be used by U-boot
like a script image file.

This adds support for a custom USB boot stage only available when the
boot mode is USB and the script file at a pre-defined address is valid.
This support was heavily copied from the Sunxi Allwinner FEL U-Boot support.

The tool pyamlboot described at [2], permits using this boot mode on boards
exposing the first USB port, either as OTG or Host port.

5 years agosandbox: Boot in U-Boot through the standard call
Simon Glass [Fri, 16 Nov 2018 01:44:08 +0000 (18:44 -0700)]
sandbox: Boot in U-Boot through the standard call

Most architectures use jump_to_image_no_args() to jump from SPL to U-Boot.
At present sandbox is special in that it jumps in its
spl_board_load_image() call. This is not strictly correct, and means that
sandbox misses out some parts of board_init_r(), just as calling
bloblist_finish(), for example.

Change spl_board_load_image() to just identify the filename to boot, and
implement jump_to_image_no_args() to actually jump to it.

sandbox: Filter arguments when starting U-Boot

The current method of starting U-Boot from U-Boot adds arguments to pass
the memory file through, so that memory is preserved. This is fine for a
single call, but if we call from TPL -> SPL -> U-Boot the arguments build
up and we have several memory files in the argument list.

Adjust the implementation to filter out arguments that we want to replace
with new ones. Also print a useful error if the exec() call fails.

5 years agosandbox: Use malloc() and free() from os layer
Simon Glass [Fri, 16 Nov 2018 01:44:06 +0000 (18:44 -0700)]
sandbox: Use malloc() and free() from os layer

At present sandbox calls malloc() from various places in the OS layer and
this results in calls to U-Boot's malloc() implementation. It is better to
use the on in the OS layer, since it does not mix allocations with the
main U-Boot code.
