* ENGR00238048: Add support for processor serial ATAG in uboot for iMX53Nitin Garg2012-12-21-0/+28
| | | | | | | Add support for Processor UID ATAG in uboot for iMX53. The UID is present in Fuses bank 0 at offset 0x20. Signed-off-by: Nitin Garg <nitin.garg@freescale.com>
* ENGR00235821 mx6: correct work flow of PFDsAnson Huang2012-12-13-0/+31
| | | | | | | | | | PFDs need to be gate/ungate after PLL lock to reset PFDs to right state. Otherwise PFDs may lose correct state in state-machine, then no output clock. For i.MX6DL and i.MX6SL, ROM have taken care of PFD396 already since the bus clock needs it. Signed-off-by: Anson Huang <b20788@freescale.com>

* ENGR00235817 mx6: use SNVS LPGPR register to store boot mode value.Zhang Jiejing2012-12-11-4/+5
| | | | | | | | | | | | | | | | | After using POR reset, the content in SRC will be reset. See RM: 63.5.1.2.3 IPP_RESET_B(POR) Because POR reset will reset most of register in IC, so use SNVS_LP General Purpose Register (LPGPR) to store the boot mode value. Below copy from SNVS_BlockGuide.pdf: The SNVS_LP General Purpose Register provides a 32 bit read write register, which can be used by any application for retaining 32 bit data during a power-down mode This Patch will use [7,8] bits of this register.

* ENGR00218972 MX6 Secure Boot, Change to dynamic HAB data authenticationEric Sun2012-08-01-18/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original secure boot implementation make a consumption that u-boot.bin will not exceed 0x2F000. With this consumption, the hab data is hard coded in linker script file to relative address 0x2F000 without causing any problem. But when this consumption don't hold, the hard coded way will cause memory region overlap and break build. So we need to change to a dynamic way of allocating hab_data. The new implementation put hab data at the next 0x1000 alignment after u-boot data and text section, instead of hard coded to 0x2F000. Similar changes is made to uImage authentication implementation. Changes in U-Boot includes: - in u-boot.lds file, change "__hab_data" to dynamic align to 0x1000 - change authenticate_image implementation, originally the uImage parameters are hard coded, now they are retrived from the "load_addr" and the image_hdr The new secure image layout: U-Boot +-------------------+ DDR_START | | | U-Boot Image | | | +-------------------+ DDR_START + UBOOT_SIZE | PADDING | +-------------------+ align to 0x1000 | CSF Data | - +-------------------+ +-- CSF + Pad, Size : 0x2000 | PADDING | - +-------------------+ uImage +-------------------+ DDR_START | | | uImage | | | +-------------------+ DDR_START + UIMAGE_SIZE | PADDING | +-------------------+ align to 0x1000 | IVT | ---- Size : 0x20 +-------------------+ | CSF Data | - +-------------------+ +-- CSF + Pad, Size : 0x2000 | PADDING | - +-------------------+ Signed-off-by: Eric Sun <jian.sun@freescale.com>

* ENGR00160621 [MX6]Workaround for reset issueAnson Huang2011-12-20-0/+25
| | | | | | | | | | | | | | | | | | | Add workaround for POR/wdog reset issue, we need to do a CORE LDO reset everytime POR/wdog reset, otherwise kernel will crash or hang when we booting more than 2 cores. Root cause is still under investigation, it is analog/power related issue, may take long time to identify the root cause, we need to add workaround to make function ready first. The flow of workaround is as below: 1. Check CORE LDO reset flag, currently stored in SNVS_LPGPR[0]; 2. If it is there, clear it, go on boot up system; If not, Set the flag, configure wdog to timeout in 0.5 seconds, then disable CORE LDO and wait for wdog timeout; This workaround will bring 0.5~1 seconds delay of booting.
