* 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>

| | | | | | | | | | | Original pad configuration don't provide enough bitfield width to hold all necessary information. For MX6Sololite, a "PAD_CTL_LVE" is needed to be configed for many pins. iomux_v3_cfg_t is re-orgnized to address this issue. PAD_CTRL is extended by 1 bit to hold the "PAD_CTL_LVE".

* 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.

* ENGR00137372 MX53: Switch back to use DCD and update DDR scriptsLily Zhang2010-12-28-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. This patch is used to switch back to use DCD for flash header instead of plug-in. This change request is due to the following reasons: 1) U-boot community doesn't accept current plug-in solution when upstreaming. 2) Plug-in isn't supported by MX53 ROM serial download mode. No effective workaround is found now. To use the same code base to support normal U-Boot and MFG tool better, adopt DCD solution firstly. 3) Current MX53 DDR scripts don't exceed the length limitation of DCD. For MX53 TO2.0 EVK/ARM2 board, raise DDR frequency to 400MHZ after VCC and VDDA voltages are raised as 1.3V. Since ARM2 CPU2 board share the same script with EVK, delete ARM2 CPU2 config files. ARM2 CPU2 board can share the same bootloader with EVK. 2. Update MX53 DDR2 scripts for TO1.0/TO2.0 EVK/ARD/ARM2 boards The script "MX53_TO2_DDR2_EVK_ARD.inc" is located under http://compass.freescale.net/livelink/livelink? func=ll&objId=221058910&objAction=browse&viewType=1 This script is published by ATX and FIL team on Dec 16th, 2010 3.

* ENGR00132909 MX53 Uboot: Support for TO2Anish Trivedi2010-11-15-7/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support new DDR script entitled "Rita_TO2_init_DDR2_CPU2_CMOS_TEST_CAL_v1.inc" for DDR2 boards including MX53 EVK, ARD, and ARM2 CPU2. These new settings did not apply to TO1. Therefore, changed the DCD for these boards to a plugin so that TO1 and TO2 can both be supported using conditional execution of new DDR settings. During bootup on TO2, DDR frequency is required to be below 400 MHz. Therefore, BOOT_CFG2[4] must be set to enable DDR at 333 MHz in ROM on all boards. Uboot determines silicon version and for TO2 boosts the VCC and VDDA voltages to 1.3V, after which the DDR frequency is also increased to 400 MHz. This requirement meant that uboot does not calibrate PLL2 anymore until the voltage is increased. Removed the calibration from lowlevel_init.S and from all mx53 include/configs files. Also required that during config_periph_clk(), only CBCMR register is touched to set source PLL. Other changes to CBCDR were removed. Switching to PLL2 bypass clk during reprogram was also removed. All these changes are required to increase DDR frequency to 400 MHz. DDR2 CPU2 board with TO1 requires the following hw cfgs: JP3 populated, and J8 set to 2-3. For DDR2 CPU2 board with TO2, both these jumpers should be depopulated. ARM2 CPU3 (with DDR3) DDR configurations were not changed. TO1 and TO2 can run well using existing DDR3 script. However, DCD was converted to plugin to align with other boards. Signed-off-by: Anish Trivedi <anish@freescale.com>
