Kconfig: rename CONFIG_SPL_USB_GADGET_SUPPORT as CONFIG_SPL_USB_GADGET

The SPL option for USB gadget should be named after the option for u-boot
(CONFIG_USB_GADGET)

imx for 2019.01

- introduce support for i.MX8M
- fix size limit for Vhybrid / pico boards
- several board fixes
- w1 driver for MX2x / MX5x

imx8m: Enable CONFIG_SPL_FIT_IMAGE_TINY for iMX8M

2019-01-01T13:12:18+00:00

If we don't define CONFIG_SPL_FIT_IMAGE_TINY, when loading images from FIT,
the SPL will record all loadables' info to u-boot's FDT. This causes
problem when HAB is enabled, because FDT's content is modified before
we authenticate it.

SPL: Add HAB image authentication to FIT

2019-01-01T13:12:18+00:00

Introduce two board level callback functions to FIT image loading process, and
a SPL_FIT_FOUND flag to differentiate FIT image or RAW image.

Implement functions in imx common SPL codes to call HAB funtion
to authenticate the FIT image. Generally, we have to sign multiple regions
in FIT image:
1. Sign FIT FDT data (configuration)
2. Sign FIT external data (Sub-images)

Because the CSF supports to sign multiple memory blocks, so that we can use one
signature to cover all regions in FIT image and only authenticate once.
The authentication should be done after the entire FIT image is loaded into
memory including all sub-images.
We use "-p" option to generate FIT image to reserve a space for FIT IVT
and FIT CSF, also this help to fix the offset of the external data (u-boot-nodtb.bin,
ATF, u-boot DTB).

The signed FIT image layout is as below:
--------------------------------------------------
|     |     |     |   |           |     |        |
| FIT | FIT | FIT |   | U-BOOT    | ATF | U-BOOT |
| FDT | IVT | CSF |   | nodtb.bin |     |   DTB  |
|     |     |     |   |           |     |        |

spl: net: dm: usb: bind the gadget before attempting to load the image

2018-12-14T16:59:09+00:00

If DM_USB_GADGET is used, the usb ethernet gadget driver must be bound to a
controller before the image can be downloaded over the network.
In u-boot this can be done with the bind command. In SPL it must be done
programmatically.

spl: fix build failure with !CONFIG_SPL_PCI_SUPPORT

2018-12-12T17:14:23+00:00

Building U-Boot with CONFIG_PCI and CONFIG_DM_PCI enabled, but
CONFIG_SPL_PCI_SUPPORT disabled, results in following linker
error:

lib/built-in.o: In function `fdtdec_get_pci_bar32':
lib/fdtdec.c:305: undefined reference to `dm_pci_read_bar32'
fdtdec.c:305:(.text.fdtdec_get_pci_bar32+0x24): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dm_pci_read_bar32'

This is because reference to dm_pci_read_bar32() remains in lib/fdtdec.c
while SPL build does not descend into drivers/pci directory in
drivers/Makefile if CONFIG_SPL_PCI_SUPPORT is not enabled.

Fix this by applying appropriate #define guards in lib/fdtdec.c.
It looks like ns16550.c has the same problem, so fixed that too.

To simplify this, CONFIG_SPL_PCI_SUPPORT is renamed to CONFIG_SPL_PCI
(enables use of CONFIG_IS_ENABLED() macro).

blk: Rework guard around part_init call

2018-12-12T17:14:22+00:00

The function part_init() will only be built when we have both
CONFIG_PARTITIONS and CONFIG_HAVE_BLOCK_DEVICE set.  Protect the call to
this function with both of these tests now.

spl: Add support for passing handoff info to U-Boot proper

2018-11-26T13:25:37+00:00

There is some basic informaton that SPL normally wants to pass through to
U-Boot, such as the SDRAM size and bank information.

Mkae use of the new bloblist structure for this. Add a new 'handoff' blob
which is set up in SPL and passed to U-Boot proper. Also adda  test for
sandbox_spl that checks that this works correctly and a new 'sb' command
to show the information passed from SPL.

spl: Add a comment to spl_set_bd()

2018-11-26T13:25:34+00:00

There is a strange feature to set global_data to a data-section variable
early in SPL. This only works if SPL actually has access to SRAM which is
not the case on x86, for eaxmple. Add a comment to this effect.

spl: Make SPL_DISABLE_BANNER_PRINT a positive option

Rather than having a negative option, make this a positive option and
enable it by default. This makes it easier to understand.
