imx: reorganize IMX code as other SOCs

2017-07-12T08:17:44+00:00

Change is consistent with other SOCs and it is in preparation
for adding SOMs. SOC's related files are moved from cpu/ to
mach-imx/.

This change is also coherent with the structure in kernel.

imx6: Add src_base structure define macro

2017-03-17T08:27:08+00:00

Instead of initializing 'struct src' to SRC_BASE_ADDR on
every function better to have global define macro.

imx: Use IMX6_BMODE_* macros instead of numericals

2017-03-17T08:27:08+00:00

Use meaningful macros IMX6_BMODE_*, instead of numerical

imx: spl: Update NAND bootmode detection bit

2017-03-17T08:27:08+00:00

BOOT_CFG1[7:4] the NAND boot mode selection is done
only when BOOT_CFG1[7] is 1 hence update the NAND
boot mode detection bit case. This information available
on Table 8-11. NAND Boot eFUSE Descriptions, from IMX6DQRM.

imx6: Add imx6_src_get_boot_mode

2017-03-17T08:27:08+00:00

For i.MX6, the bootmode determine code is part of spl_boot_device,
but there is might be a possibility for other part the code need to
check the desired boot mode for adding new functionalities like
modeboot env variable, or changing boot order etc.

So introduced imx6_src_get_boot_mode which actually reading the
boot mode register for desired modes.

More cleanup will be add in future patches.

imx_common: check for bmode Serial Downloader

2017-01-27T09:40:16+00:00

Before commit 81c4eccb55cc ("imx: mx6: fix USB bmode to use
reserved value") a non-reserved value has been used to trigger
Serial Downloader using bmode, which translated to a GPR9 value
of 0x10. However, on some boards the non-reserved value lead to
unreliable bmode command. With the above mentioned commit, U-boot
switched to use [7:4] b0001, which translates to GPR9 0x10 for
Serial Downloader mode. Check for the new value and classify it
as Serial Downloader mode.

SPL: Adjust more debug prints for ulong entry_point

2017-01-11T15:45:48+00:00

With entry_point now being an unsigned long we need to adapt the last
two debug prints to use %lX not %X.

arm: imx: add HAB authentication of image to SPL boot

2017-01-02T16:04:38+00:00

When using HAB as secure boot mechanism on Wandboard, the chain of
trust breaks immediately after the SPL. As this is not checking
the authenticity of the loaded image before jumping to it.

The HAB status output will not be implemented in SPL as it adds
a lot of strings that are only required in debug cases. With those
it exceeds the maximum size of the available OCRAM (69 KiB).

The SPL MISC driver support must be enabled, so that the driver can use OTP fuse
to check if HAB is enabled.

ARM: mx6: add MMC2 boot device detection support in SPL

2016-11-29T15:31:53+00:00

Check BOOT_CFG2[3:4] to determine which SD/MMC port is selected to boot
from. If MMC2 is selected return BOOT_DEVICE_MMC2. In all other cases
return BOOT_DEVICE_MMC1, as we do not have corresponding macro for MMC3
and MMC4.
