* ARM: mxs: Document the power block initializationMarek Vasut2013-09-10-0/+209

* mx6: Fix calculation of emi_slow clock rateAndrew Gabbasov2013-09-10-4/+4
| | | | | | | | | | | | | This is porting of Freescale's patch from version imx_v2009.08_3.0.35_4.0.0, that fixes the obvious mistype of bits offset macro name (ACLK_EMI_PODF_OFFSET was used instead of ACLK_EMI_SLOW_PODF_OFFSET). Using the occasion, change the variable name 'emi_slow_pof' to more consistent 'emi_slow_podf'.

| | | | | | | | | | | | | | | | | | | | | | | | | | Some _CLKGATE_MASK and _FRAC_MASK macros were wrong for PFD_480 and the PFD_528 macros were missing. Fortunately, the incorrect macros weren't being used. Since both the PFD_480 and PFD_528 registers have the same structure, and the fields are identical for [0..3] in bytes [0..3], so a single set of macros will suffice.

| * ARM: mxs: rename function that sets AUTO_RESTART flagHector Palacios2013-08-31-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AUTO_RESTART flag of HW_RTC_PERSISTENT0 register will power up the chip automatically 180ms after power down. This bit must be enabled by the boot loader to ensure the target can start upon hardware reset or watchdog reset even when powered from a battery. Currently the function named 'mxs_power_clear_auto_restart()' is setting this flag although the 'clear' in its name suggest the opposite. This patch renames the function to 'mxs_power_set_auto_restart()' and removes the comment about EVK revision A which was confusing because the function indeed was setting the flag.

| * ARM: mxs: tools: Add mkimage support for MXS bootstreamMarek Vasut2013-08-31-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add mkimage support for generating and verifying MXS bootstream. The implementation here is mostly a glue code between MXSSB v0.4 and mkimage, but the long-term goal is to rectify this and merge MXSSB with mkimage more tightly. Once this code is properly in U-Boot, MXSSB shall be deprecated in favor of mkimage-mxsimage support. Note that the mxsimage generator needs libcrypto from OpenSSL, I therefore enabled the libcrypto/libssl unconditionally.

Device reference manual provides a scheme that allows the I2C master controller to generate nine SCL pulses, which enable an I2C slave device that held SDA low to release SDA. However, due to this erratum, this scheme no longer works. In addition, when I2C is used as a source of the PBL, the state machine is not able to recover. At the same time, delete the reduplicative definition of SVR_VER and SVR_REV. The SVR_REV is the low 8 bits rather than the low 16 bits of svr. And we use the CONFIG_SYS_FSL_A004447_SVR_REV macro instead of hard-code value 0x10, 0x11 and 0x20. The CONFIG_SYS_FSL_A004447_SVR_REV = 0x00 represents that one version of platform has this I2C errata. So enable this errata by IS_SVR_REV(svr, maj, min) function.

Since "the beginning" of usage of the SABRE Lite and Nitrogen6x boards, DVI detection has been somewhat broken. Some (most) DVI monitors don't produce the "HPD" bit in the PHY_STAT0 register, but do show proper toggling of the RX_SENSE0..3 bits. Creating a new the bit-mask to include all five bits and modifying the 'hdmidet' command and internal detection routines allows these monitors to function properly in U-Boot. A related patch to our kernels allows things to work under Linux: https://github.com/boundarydevices/linux-imx6/commit/7d8752905c118af9063738a533227de0b2f6ecd4 Signed-off-by: Robert Winkler <robert.winkler@boundarydevices.com> Acked-by: Stefano Babic <sbabic@denx.de>
