| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When booting from USB peripheral boot, the bootrom will not properly deinit the MUSB controller, which doesn't clearly indicate an USB disconnection to the host and leaves U-Boot to deal with the state of the previous USB session. On some host controller drivers (e.g. xhci_hcd), this ends up in a failure during set address, caused by the lack of proper disconnection notification. Resetting the controller early in U-Boot notifies the host of the disconnection and doesn't hurt other use cases.

| * | | Exynos: Fix L2 cache timings on Exynos5420 and Exynos5800Doug Anderson2015-02-28-95/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was found that the L2 cache timings that we had before could cause freezes and hangs. We should make things more robust with better timings. Currently the production ChromeOS kernel applies these timings, but it's nice to fixup firmware too (and upstream probably won't take our kernel hacks). This also provides a big cleanup of the L2 cache init code avoiding some duplication. The way things used to work: * low_power_start() was installed by the SPL (both at boot and resume time) and left resident in iRAM for the kernel to use when bringing up additional CPUs. It used configure_l2_ctlr() and configure_l2_actlr() when it detected it was on an A15. This was needed (despite the L2 cache registers being shared among all A15s) because we might have been the first man in after the whole A15 cluster was shutdown. * secondary_cores_configure() was called on at boot time and at resume time. Strangely this called configure_l2_ctlr() but not configure_l2_actlr() which was almost certainly wrong. Given that we'll call both (see next bullet) later in the boot process it didn't matter for normal boot, but I guess this is how L2 cache settings got set on 5420/5800 (but not 5250?) at resume time. * exynos5_set_l2cache_params() was called as part of cache enablement. This should happen at boot time (normally in the SPL except for USB boot where it happens in main U-Boot). Note that the old code wasn't setting ECC/parity in the cache enablement code but we happened to get it anyway because we'd call secondary_cores_configure() at boot time. For resume time we'd get it anyway when the 2nd A15 core came up. Let's make this a whole lot simpler. Now we always set these parameters in the same place for all boots and use the same code for setting up secondary CPUs. Intended net effects of this change (other than cleanup): * Timings go from before: data: 0 cycle setup, 3 cycles (0x2) latency tag: 0 cycle setup, 3 cycles (0x2) latency after: data: 1 cycle setup, 4 cycles (0x3) latency tag: 1 cycle setup, 4 cycles (0x3) latency * L2ACTLR is properly initted on 5420/5800 in all cases. One note is that we're still relying on luck to keep low_power_start() working. The compiler is being nice and not storing anything on the stack. Another note is that on its own this patch won't help to fix cache settings in an RW U-Boot update where we still have the RO SPL. The plan for that is: * Have RW U-Boot re-init the cache right before calling the kernel (after it has turned the L2 cache off). This is why the functions are in a header file instead of lowlevel_init.c. * Have the kernel save the L2 cache settings of the boot CPU and apply them to all other CPUs. We get a little lucky here because the old code was using "|=" to modify the registers and all of the bits that it's setting are also present in the new settings (!). That means that when the 2nd CPU in the A15 cluster comes up it doesn't actually mess up the settings of the 1st CPU in the A15 cluster. An alternative option is to have the kernel write its own low_power_start() code.

In low_power_start, cores check the reset status and if true they clear the jump flag and jump back to 0x0. The A7 cores do jump to 0x0 but consider following instructions as a Thumb instructions which in turn makes them loop inside the iROM code instead of jumping to power_down_core. This issue is fixed by replacing the "mov pc" instruction with a "bx" instruction which switches state along with the jump to make the execution unit consider the branch target as an ARM instruction.

| * | | Exynos542x: Fix secondary core booting for thumbAkshay Saraswat2015-02-28-1/+4

Only one core came up out of 4. This was happening because the code relocated to the address 0x02073000 by the primary core was an ARM asm code which was executed by the secondary cores as if it was a thumb code. This patch fixes the issue of secondary cores considering relocated code as Thumb instructions and not ARM instructions by jumping to the relocated with the help of "bx" ARM instruction. "bx" instruction changes the 5th bit of CPSR which allows execution unit to consider the following instructions as ARM instructions.

Logic of the workaround: Step-1: iROM code checks value at address 0x2020028. Step-2: If value is 0xc9cfcfcf, it jumps to the address (0x202000+CPUid*4), else, it continues executing normally. Step-3: Primary core puts secondary cores in WFE and store 0xc9cfcfcf in 0x2020028 and jump address (pointer to function low_power_start) in (0x202000+CPUid*4). Step-4: When secondary cores recieve event signal they jump to this address and continue execution.

When U-boot comes up, all secondary cores appear powered on, which is undesirable and causes side effects while initializing these cores in kernel. Secondary core power down happens in following steps: Step-1: After Exynos power-on, primary core starts executing first. Step-2: In iROM code every core has to check 2 flags i.e. addresses 0x02020028 & 0x02020004. Step-3: Initially 0x02020028 is 0 for all cores and 0x02020004 has a jump address for primary core and 0 for all secondary cores. Step-4: Therefore, primary core follows normal iROM execution and jumps to BL1 eventually, whereas all secondary cores enter WFE. Step-5: When primary core comes into function secondary_cores_configure, it puts pointer to function power_down_core into 0x02020004 and provides DSB and SEV for all cores so that they may come out of WFE and jump to power_down_core function. Step-6: And ultimately because of power_down_core all secondary cores shut-down.

On that SoC, MPLL is already running on the power-on reset and it makes sense to stop the PLL at early boot-up. On the other hand, PH1-Pro4(R) does not have SC_MPLLOSCCTL register, so this function has no point. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
| * | | ARM: UniPhier: consolidate MEMCONF setting codeMasahiro Yamada2015-03-01-141/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code is duplicated in ph1-ld4/sg_init.c and ph1-pro4/sg_init.c. Merge the same code into a new file, memconf.c. The helper functions no longer have to be placed in the header file. Also, move them into memconf.c. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
| * | | ARM: UniPhier: switch to 1CS support cardMasahiro Yamada2015-03-01-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 3CS support card (CONFIG_DCC_MICRO_SUPPORT_CARD) used to be used very often before, but it is recently getting a minority. Swith to the 1CS support card (CONFIG_PFC_MICRO_SUPPORT_CARD). Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
| * | | ARM: UniPhier: support 1CS support card for all the UniPhier SoCsMasahiro Yamada2015-03-01-121/+189
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two support card variants are used with UniPhier reference boards: - 1 chip select support card (original CPLD) - 3 chip selects support card (ARIMA-compatible CPLD) Currently, the former is only supported on PH1-Pro4, but it can be expanded to PH1-LD4, PH1-sLD8 with a little code change.

| * | | ARM: UniPhier: switch to xHCI for PH1-Pro4Masahiro Yamada2015-03-01-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PH1-Pro4 includes both EHCI and xHCI IP cores. Unfortunately, U-Boot cannot enable EHCI and xHCI support simultaneously. Some users may wish Super-Speed connection. Disable CONFIG_USB_EHCI_HCD and enable CONFIG_USB_XHCI_HCD. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
