* MLK-11408-2 imx: mx7d: Isolate 26 IP resources to domain 0 for A coreYe.Li2015-08-25-0/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | In current design, if any peripheral was assigned to both A7 and M4, it will receive ipg_stop or ipg_wait when any of the 2 platforms enter low power mode. We will have a risk that, if A7 enter wait, M4 enter stop, peripheral will have chance to get ipg_stop and ipg_wait asserted same time. There are 26 peripherals impacted by this IC issue: SIM2(sim2/emvsim2) SIM1(sim1/emvsim1) UART1/UART2/UART3/UART4/UART5/UART6/UART7 SAI1/SAI2/SAI3 WDOG1/WDOG2/WDOG3/WDOG4 GPT1/GPT2/GPT3/GPT4 PWM1/PWM2/PWM3/PWM4 ENET1/ENET2 Software Workaround: The solution is set M4 to a different domain with A core. So the peripherals are not shared by them. This way requires the uboot implemented the RDC driver and set the 26 IPs above to domain 0 only. CM4 image will set the M4 to domain 1 only. This patch enables the CONFIG_MXC_RDC for mx7d SABRESD board and ARM2 boards, and setup the 26 IP resources to domain 0. Signed-off-by: Ye.Li <B37916@freescale.com>

* tools/imximage: set DCD pointer to NULL when its length is 0Baruch Siach2015-08-20-1/+5
| | | | | | | | | | | | | | | | | | | | | | | When dcd_len is 0 the Write Data command that the set_dcd_rst_v2() routine generates is empty. This causes HAB to complain that the command is invalid. --------- HAB Event 1 ----------------- event data: 0xdb 0x00 0x0c 0x41 0x33 0x06 0xc0 0x00 0xcc 0x00 0x04 0x04 To fix this set the DCD pointer in the IVT to NULL in this case. The DCD header itself is still needed for detect_imximage_version() to determine the image version.

| | | | | | | | | | This mx7d 19x19 lpddr2 arm2 board is based on 19x19 lpddr3 arm2 board with DDR changed to 512M LPDDR2. We added DDR script for LPDDR2 and a new u-boot build target: mx7d_19x19_lpddr2_arm2_config LPDDR2 script source: lpddr2_0_1.ds Signed-off-by: Ye.Li <B37916@freescale.com>
* MLK-11367 imx: mx6ul: Add cma bootargs for 6ul 9x9 boardYe.Li2015-08-17-0/+6
| | | | | | | | | | | Since the i.MX6ul 9x9 evk board only has 256MB LPDDR2, while the CMA size used in kernel configuration is 320MB, so we have to set another value for the 9x9 evk board. This patch sets the cma=96M bootargs to in uboot. So the kernel will overwrite to use the new value. Signed-off-by: Ye.Li <B37916@freescale.com>

| | | | | | | | | | | | | | The i.mx6ul 9x9 EVK shares the same base board with 6ul 14x14 EVK with two main changes on CPU board: 1. Change to use pfuze 3000. 2. Use 256MB LPDDR2 memory. This patch uses a macro CONFIG_6UL_9X9_LPDDR2 to distinguish the changes above, basing on 14x14 EVK board level codes.

| | | | | | | | | | As we need to support LPSR mode resume and due to hardware design requirement, DCD can NOT put DRAM exit from retention mode, so only plug in mode can do that to support LPSR mode, so enabled plug in mode by default for imx7d 12x12-lpddr3-arm2 board.

| | | | | | | | | | | | For imx7d 12x12-lpddr3-arm2 board, when system enters LPSR mode and waked up, ARM core will be reset and uboot needs to be executed first, the LPSR register contains a resume entery, if this entry is non-zero, then it means it is a resume from LPSR mode, uboot plug in code needs to make DRAM exit from retention mode then jump to the entry directly, otherwise, it is a cold boot, normal boot process will be performed.

If 'splashpos' env is set, will choose the pos from 'splashpos'. 5. The image size should not be bigger than screen total pixel size. 6. Implement board_setup_logo_file in board/freescale/common/epdc_setup.c 7. Introudce function prototype for board_setup_logo_file. Note: i.MX7D EPDC supports advanced mode and standard mode. Since current PXP in uboot for i.MX7D not ready, only support standard mode now. advanced and standard mode needs waveform firmware's support. Signed-off-by: Peng Fan <Peng.Fan@freescale.com>

* MLK-11304 MX6 SabreSD: Disable HDMI detectPeng Fan2015-07-31-1/+1
| | | | | | | | | | | | | | | As the HDMI splash screen feature is not well supported, we should not set it to be the default display. In case, users leave the 'panel' uboot environment variable empty and connect the board with a HDMI monitor, the HDMI detect funtion will work and enable the HDMI splash screen. So, this patch disables HDMI detect function so that users may only explicitly set the 'panel' variable to be 'HDMI' to use HDMI splash screen.

But, we need pull-up for CD/VSELECT/RST. Also some board provides external pull-down/up, we'd better use internal pull-up for these pad settings.

* MLK-11059 imx: HAB unable to support Encrypted boot for 4096-bit keysUlises Cardenas2015-06-16-24/+84
| | | | | | | | Abstracted the CSF size in imximage from a hardcoded value to a config setting CONFIG_CSF_SIZE. This configuration is only enabled for secure boot. Increased the size of the CSF default allocation to 0x4000. This size covers the event the worst case of 4906-bits keys.
* MLK-11101 imx: mx6: Move the set_wdog_reset out of CONFIG_LDO_BYPASS_CHECKYe.Li2015-06-12-22/+22
| | | | | | | | Since the 6ul does not enable the CONFIG_LDO_BYPASS_CHECK, but have to use the set_wdog_reset function. Need to move the funciton out of CONFIG_LDO_BYPASS_CHECK to resolve build issue. Signed-off-by: Ye.Li <B37916@freescale.com>
* MLK-11099 imx: mx6ul: Enable the Watchdog WDOG_B signal outputYe.Li2015-06-12-0/+2
| | | | | | | | When using watchdog timeout in kernel, the reset does not output the WDOG_B signal, so the power supply won't be reset. To solve the problem, we enable it in u-boot. Signed-off-by: Ye.Li <B37916@freescale.com>

* MLK-11035 imx: mx6 update thermal slope factorsPeng Fan2015-06-12-2/+2
| | | | | | | | | | | | | | | | | | | | From temp sensor guys: " I confirmed the math with him(had do the accuracy study) today. The new, final equation is: Tmeas = (Nmeas - n1) / slope + t1 + offset n1= fused room count t1= 25 offset=3.580661 slope= 0.4148468 – 0.0015423*n1 " 87723f903454aaf17336e0fe9098ea7911c19f3c update the thermal with not accurate slope parameters. This patch fix it. Signed-off-by: Peng Fan <Peng.Fan@freescale.com>
