* MLK-12495 mx6: Add LDO bypass supportYe Li2017-04-05-0/+3
| | | | | | | | | | | | | | | | Port LDO bypass support from v2015 to support the features: 1. Add check for 1.2GHz core speed. If Speed grading fuse is for 1.2GHz, enable LDO bypass and setup PMIC voltages. LDO bypass is dependent on the flatten device tree file. 2. We set WDOG_B in set_anatop_bypass() before, because it is the only case, but now on i.mx6sabreauto board, we didn't use ldo-bypass mode, but have to use WDOG_B to reboot whole board, so split these code to independent function so that board file can call it freely.

| | | | | | | | | | | | Apply errata based on PL310 version instead of compile time. Also set Prefetch offset to 15, since it improves memcpy performance by 35%. Don't enable Incr double Linefill enable since it adversely affects memcpy performance by about 32MB/s and reads by 90MB/s. Tested with 4K to 16MB sized src and dst aligned buffer.

| | | | | | | | | | | | | | | | | | | From i2c spec, if device pull down the SDA line that causes i2c bus dead, host can send out 9 clock to let device release SDA. But for some special device like pfuze100, it pull down SDA line and the solution cannot take effort.

* imx_common: check for bmode Serial DownloaderStefan Agner2017-01-27-2/+4
| | | | | | | | | | | | | | | | | 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.

* arm: imx: add HAB authentication of image to SPL bootSven Ebenfeld2017-01-02-59/+105
| | | | | | | | | | | | | | | | | | | | | 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.

* imx: imx-common: power down lcdif before boot osPeng Fan2015-11-12-0/+3
| | | | | | | | | | | | | | Need to call lcdif_power_down to make lcdif in initial state before kernel boot. Similar issue for uboot reset with lcdif enabled, system will hang after serveral times resetting. Need to let lcdif initial state to make all go well.

* imx: hab: add mx7 secure boot supportAdrian Alonso2015-10-30-2/+4
| | | | | | | | | | | | | Add mx7 secure boot support, add helper macro IS_HAB_ENABLED_BIT to get the corresponding bit mask per SoC (mx7 or mx6) to identify if securue boot feature is enabled/disabled. On authenticate_image only check for mmu enabled on mx6 SoC to force pu_irom_mmu_enabled so ROM code can perform mmu cache flush mx7 SoC ROM code does not have this issue as ROM enables cache support based on fuse settings.
