| * | | Exynos542x: Add workaround for ARM errata 799270Akshay Saraswat2015-02-28-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds workaround for the ARM errata 799270 which says "If the L2 cache logic clock is stopped because of L2 inactivity, setting or clearing the ACTLR.SMP bit might not be effective. The bit is modified in the ACTLR, meaning a read of the register returns the updated value. However the logic that uses that bit retains the previous value."

| * | | Exynos542x: CPU: Power down all secondary coresAkshay Saraswat2015-02-28-0/+164
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds code to shutdown secondary cores. 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.

| * | | Exynos542x: Config: Add various configsAkshay Saraswat2015-02-28-0/+16
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds "iRAM, CPU state and low power" configs which are the addresses acting as flag registers. iROM code checks CONFIG_LOWPOWER_FLAG address. If it is equal to CONFIG_LOWPOWER_EN then it jumps to the address (0x02020000+CPUID*4). This is a part of iROM logic. Rest other flags are being used at various places during kernel switching and reset. They are nowhere documented because they are part programming. These configs are serving as flags for us because they are representing the addresses in iRAM which we are using for storing and extracting CPU Status and GIC status.

| * | | ARM: UniPhier: remove SSC_WAY_SIZE and SSC_NUM_ENTRIES macrosMasahiro Yamada2015-03-01-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each way of the system cache has 256 entries for PH1-Pro4 and older SoCs, whereas 512 entries for PH1-Pro5 and newer SoCs. The line size is still 128 byte. Thus, the way size is 32KB/64KB for old/new SoCs. To keep lowlevel_init SoC-independent, set BOOT_RAM_SIZE to the constant value 32KB. It is large enough for temporary RAM and should work for all the SoCs of UniPhier family. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
| * | | ARM: UniPhier: remove stop_mpll() from PH1-Pro4 PLL initializationMasahiro Yamada2015-03-01-21/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function was intended for MN2WS0235 (what we call PH1-Pro4TV). 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: reset NAND core in SPL for non-NAND boot modeMasahiro Yamada2015-03-01-0/+5

(The bit 2 of SC_RSTCTRL is default to one.) This causes a fatal problem on the NAND controller of PH1-LD4. For that SoC, the NAND I/O pins are not set up yet at the power-on reset except the NAND boot mode. As a result, the NAND controller begins automatic device scanning with wrong I/O pins and finally hangs up. Actually, U-Boot dies after printing "NAND:" on the console unless the boot mode latch detected the NAND boot mode. To work around this problem, reset the NAND core in SPL for non-NAND boot modes. If CONFIG_NAND_DENALI is enabled, the reset signal is deasserted again in U-Boot proper. At this time, I/O pins have been correctly set up, the device scanning should succeed.
