* sunxi: dram: Configurable MBUS clock speed (use PLL5 or PLL6)Siarhei Siamashka2014-08-12-14/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sun5i hardware (Allwinner A13) introduced configurable MBUS clock speed. Allwinner A13 uses only 16-bit data bus width to connect the external DRAM, which is halved compared to the 32-bit data bus of sun4i (Allwinner A10), so it does not make much sense to clock a wider internal bus at a very high speed. The Allwinner A13 manual specifies 300 MHz MBUS clock speed limit and 533 MHz DRAM clock speed limit. Newer sun7i hardware (Allwinner A20) has a full width 32-bit external memory interface again, but still keeps the MBUS clock speed configurable. Clocking MBUS too low inhibits memory performance and one has to find the optimal MBUS/DRAM clock speed ratio, which may depend on many factors: http://linux-sunxi.org/A10_DRAM_Controller_Performance This patch introduces a new 'mbus_clock' parameter for the 'dram_para' struct and uses it as a desired MBUS clock speed target. If 'mbus_clock' is not set, 300 MHz is used by default to match the older hardcoded settings. PLL5P and PLL6 are both evaluated as possible clock sources. Preferring the one, which can provide higher clock frequency that is lower or equal to the 'mbus_clock' target. In the case of a tie, PLL5P has higher priority. Attempting to set the MBUS clock speed has no effect on sun4i, but does no harm either.

* sunxi: dram: Re-introduce the impedance calibration ond ODTSiarhei Siamashka2014-08-12-0/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | The DRAM controller allows to configure impedance either by using the calibration against an external high precision 240 ohm resistor, or by skipping the calibration and loading pre-defined data. The DRAM controller register guide is available here: http://linux-sunxi.org/A10_DRAM_Controller_Register_Guide#SDR_ZQCR0 The new code supports both of the impedance configuration modes: - If the higher bits of the 'zq' parameter in the 'dram_para' struct are zero, then the lowest 8 bits are used as the ZPROG value, where two divisors encoded in lower and higher 4 bits. One divisor is used for calibrating the termination impedance, and another is used for the output impedance. - If bits 27:8 in the 'zq' parameters are non-zero, then they are used as the pre-defined ZDATA value instead of performing the ZQ calibration. Two lowest bits in the 'odt_en' parameter enable ODT for the DQ and DQS lines individually. Enabling ODT for both DQ and DQS means that the 'odt_en' parameter needs to be set to 3.

| | | | | | | | | | | | The old 'await_completion' function is not sufficient, because in some cases we want to wait for bits to be cleared, and in the other cases we want to wait for bits to be set. So split the 'await_completion' into two new 'await_bits_clear' and 'await_bits_set' functions.

| | | | | | | | | | | The older differences were likely justified by the need to mitigate the CKE delay timing violations on sun4i/sun5i.

* sunxi: dram: Remove broken impedance and ODT configuration codeSiarhei Siamashka2014-08-12-27/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can safely remove it, because none of the currently supported boards uses these features. The existing implementation had multiple problems: - unnecessary code duplication between sun4i/sun5i/sun7i - ZQ calibration was never initiated explicitly, and could be only triggered by setting the highest bit in the 'zq' parameter in the 'dram_para' struct (this was never actually done for any of the known Allwinner devices). - even if the ZQ calibration could be started, no attempts were made to wait for its completion, or checking whether the default automatically initiated ZQ calibration is still in progress - ODT was only ever enabled on sun4i, but not on sun5i/sun7i Additionally, SDR_IOCR was set to 0x00cc0000 only on sun4i. There are some hints in the Rockchip Linux kernel sources, indicating that these bits are related to the automatic I/O power down feature, which is poorly understood on sunxi hardware at the moment. Avoiding to set these bits on sun4i too does not seem to have any measurable/visible impact. The impedance and ODT configuration code will be re-introdeced in one of the next comits.

* sunxi: dram: Fix CKE delay handling for sun4i/sun5iSiarhei Siamashka2014-08-12-7/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before driving the CKE pin (Clock Enable) high, the DDR3 spec requires to wait for additional 500 us after the RESET pin is de-asserted. The DRAM controller takes care of this delay by itself, using a configurable counter in the SDR_IDCR register. This works in the same way on sun4i/sun5i/sun7i hardware (even the default register value 0x00c80064 is identical). Except that the counter is ticking a bit slower on sun7i (3 DRAM clock cycles instead of 2), resulting in longer actual delays for the same settings. This patch configures the SDR_IDCR register for all sun4i/sun5i/sun7i SoC variants and not just for sun7i alone. Also an explicit udelay(500) is added immediately after DDR3 reset for extra safety. This is a duplicated functionality. But since we don't have perfect documentation, it may be reasonable to play safe. Half a millisecond boot time increase is not that significant. Boot time can be always optimized later. Preferebly by the people, who have the hardware equipment to check the actual signals on the RESET and CKE lines and verify all the timings. The old code did not configure the SDR_IDCR register for sun4i/sun5i, but performed the DDR3 reset very early for sun4i/sun5i. This resulted in a larger time gap between the DDR3 reset and the DDR3 initialization steps and reduced the chances of CKE delay timing violation to cause real troubles.

* sunxi: dram: Respect the DDR3 reset timing requirementsSiarhei Siamashka2014-08-12-2/+7
| | | | | | | | | | | | | | The RESET pin needs to be kept low for at least 200 us according to the DDR3 spec. So just do it the right way. This issue did not cause any visible major problems earlier, because the DRAM RESET pin is usually already low after the board reset. And the time gap before reaching the sunxi u-boot DRAM initialization code appeared to be sufficient.

* sunxi: dram: Remove broken super-standby remnantsSiarhei Siamashka2014-08-12-46/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | If the dram->ppwrsctl (SDR_DPCR) register has the lowest bit set to 1, this means that DRAM is currently in self-refresh mode and retaining the old data. Since we have no idea what to do in this situation yet, just set this register to 0 and initialize DRAM in the same way as on any normal reboot (discarding whatever was stored there). This part of code was apparently used by the Allwinner boot0 bootloader to handle resume from the so-called super-standby mode. But this particular code got somehow mangled on the way from the boot0 bootloader to the u-boot-sunxi bootloader and has no chance of doing anything even remotely sane. For example: 1. in the original boot0 code we had "mctl_write_w(SDR_DPCR, 0x16510000)" (write to the register) and in the u-boot it now looks like "setbits_le32(&dram->ppwrsctl, 0x16510000)" (set bits in the register) 2. in the original boot0 code it was issuing three commands "0x12, 0x17, 0x13" (Self-Refresh entry, Self-Refresh exit, Refresh), but in the u-boot they have become "0x12, 0x12, 0x13" (Self-Refresh entry, Self-Refresh entry, Refresh) Signed-off-by: Siarhei Siamashka <siarhei.siamashka@gmail.com> Acked-by: Ian Campbell <ijc@hellion.org.uk> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
* sunxi: dram: Remove useless 'dramc_scan_dll_para()' functionSiarhei Siamashka2014-08-12-124/+1
| | | | | | | | | | | | | | | | | | | | The attempt to do DRAM parameters calibration in 'dramc_scan_dll_para()' function by trying different DLL adjustments and using the hardware DQS gate training result as a feedback is a great source of inspiration, but it just can't work properly the way it is implemented now. The fatal problem of this implementation is that the DQS gating window can be successfully found for almost every DLL delay adjustment setup that gets tried. Thus making it unable to see any real difference between 'good' and 'bad' settings. Also this code was supposed to be only activated by setting the highest bit in the 'dram_tpr3' variable of the 'dram_para' struct (per-board dram configuration). But none of the linux-sunxi devices has ever used it for real. Basically, this code is just a dead weight.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This generic $bootcmd, and associated support macros, automatically searches a defined set of storage devices (or network protocols) for an extlinux configuration file or U-Boot boot script in various standardized locations. Distros that install such a boot config file/script in those standard locations will get easy-to-set-up booting on HW that enables this generic $bootcmd. Boards can define the set of devices from which boot is attempted, and the order in which they are attempted. Users may later customize this set/order by edting $boot_targets. Users may interrupt the boot process and boot from a specific device simply by executing e.g.: $ run bootcmd_mmc1 or: $ run bootcmd_pxe This patch was originally written by Dennis Gilmore based on Tegra and rpi_b boot scripts. I have made the following modifications since then: * Boards must define the BOOT_TARGET_DEVICES macro in order to specify the set of devices (and order) from which to attempt boot. If needed, we can define a default directly in config_distro_bootcmd.h. * Removed $env_import and related variables; nothing used them, and I think it's better for boards to pre-load an environment customization file using CONFIG_PREBOOT if they need. * Renamed a bunch of variables to suit my whims:-) Signed-off-by: Dennis Gilmore <dennis@ausil.us> Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Marek Vasut <marex@denx.de> Acked-by: Simon Glass <sjg@chromium.org>
