It is possible for jitter to increase and cause the PLL to unlock when the temperature delta from the time the PLL is calibrated exceeds +56C/-66C when using X VDD of 1.35 V (or +70C/-80C when using XnVDD of 1.5 V). No issues are seen with LC VCO. Only the protocols using Ring VCOs are impacted. Workaround: For all 1.25/2.5/5 GHz protocols, use LC VCO instead of Ring VCO, this need to use alternate serdes protocols. The alternate option has the same functionality as the original option; the only difference being LC VCO rather than Ring VCO.

Date: Wed, 28 May 2014 14:18:55 +0530 Subject: powerpc/serdes: Add the workaround for erratum A-007186 SerDes PLL is calibrated at reset. When the junction temperature delta from the time the PLL is calibrated exceeds +56C/-66C, jitter may increase and can cause PLL to unlock. This workaround overwrite the SerDes registers with new values, to calibrate SerDes registers. These values are known to work fine for all temperature ranges. This workaround is valid for B4, T4 and T2 platforms, so added in their config.

T1040 has 36 bit physical addressing, TDM DMAC register are 32 bit wide but need to store address of CCSR space which lies beyond 32 bit address range. This workaround creats a LAW to enable access of TDM DMA to CCSR by mapping CCSR to overlap with DDR. A hole of 16M is created in memory using device tree.

One is SPL which is roughly: reset, cpu_init_crit, lowlevel_init, s_init, sdram_init, _main, board_init_f from SPL, ... then U-Boot loads. The other is a memory-mapped XIP case (NOR or QSPI) where we do not run an SPL. In this case we go, roughly: reset, cpu_init_crit, lowlevel_init, s_init, _main, regular board_init_f. In the first case s_init will set a valid gd and then be able to call sdram_init which in many cases will need i2c (which needs a valid gd for gd->cur_i2c_bus). In this second case we must (and are able to and should) defer sdram_init() into dram_init() called by board_init_f as gd will have been set in _main and cleared in board_init_f.

When SPL booting, this is handled by setting gd to point to SRAM in s_init. However in the cases where we are loaded directly by ROM (memory mapped NOR or QSPI) we need to make use of the normal hooks to slightly delay these calls.

This is somewhat odd and problematic as some of these bits are UNKNOWN at reset and may differ across CPUs (which may cause an OS at EL1 to observe time going backwards across CPUs). This patch instead initialises cntvoff_el2 with xzr, giving the register a consistent value of zero on all CPUs.

All characterization environments may not cope up with h/w read leveling enabled, so we must disable this. Also, disabling h/w read leveling improves the MIF LVcc value (LVcc value is the value at which DDR will fail to work properly). Improving LVcc means we have enough voltage margin for MIF. When h/w leveling is enabled, we have almost zero volatge margin.

If we stop CLKM when sampling it the glitches all go away, so we'll do that as per Samsung suggestion. We also check the "is it locked" bits of PHY_CON13 and loop until they show the the value sampled actually represents a locked value. It doesn't appear that the glitching and "is it locked" are related, but it seems wise to wait until the PHY tells us the value is good before we use it. In practice we will not loop more than a couple times (and usually won't loop at all).

However, if later a driver activates the timeout setting the reset to a valid value, the old reset value with zero is still valid for the first access. In fact, the timeout block loads the reset counter after a successful access. Found on a am335x board with a FPGA connected to the GPMC bus together with the NAND. When the FPGA driver in kernel activates the timeout, the system hangs at the first access by the NAND driver.

The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF images and u-boot, and does this for virtual platforms by using semihosting. This commit extends this idea by allowing u-boot to also use semihosting to load the kernel/ramdisk/dtb. This eliminates the need for a bootwrapper and produces a more realistic boot sequence with virtual models. Though the semihosting code is quite generic, support for armv7 in fastmodel is less useful due to the wide range of available silicon and the lack of a free armv7 fastmodel, so this change contains an untested armv7 placeholder for the service trap opcode. Please refer to doc/README.semihosting for a more detailed description of semihosting and how it is used with the armv8 virtual platforms.

German Rivera" Date: Mon, 23 Jun 2014 15:15:55 -0700 Subject: armv8/fsl-lsch3: Add support to load and start MC Firmware Adding support to load and start the Layerscape Management Complex (MC) firmware. First, the MC GCR register is set to 0 to reset all cores. MC firmware and DPL images are copied from their location in NOR flash to DDR. MC registers are updated with the location of these images. Deasserting the reset bit of MC GCR register releases core 0 to run. Core 1 will be released by MC firmware. Stop bits are not touched for this step. U-boot waits for MC until it boots up. In case of a failure, device tree is updated accordingly. The MC firmware image uses FIT format. Signed-off-by: J.

The code in cpu_init.c accessed them always as 32-bit, effectively creating a wrong memory access on M5235. Fixed that by choosing out_be16/out_be32 depending on whether CONFIG_M5235 is defined or not.
