2016-12-09arm: armv7: add us timer for bootstagePatrick Delaunay
solve issue when bootstage is used with armV7 generic timer first call of timer_get_boot_us() use the function get_timer() before timer initialization (arch.timer_rate_hz = 0) => div by 0 Commit-notes When I activate bootstage on ARMV7 architecture with platform using the generic armv7 timer defined in file ./arch/arm/cpu/armv7m/timer.c I have a issue because gd->arch.timer_rate_hz = 0 For me the get_timer() function should not used before timer_init (which initialize gd->arch.timer_rate_hz) at least for the ARMV7 timer. But in the init sequence, the first bootstage fucntion is called before timer_init and this function use the timer function. For me it is a error in the generic init sequence : mark_bootstage is called before timer_init. static init_fnc_t init_sequence_f[] = { .... arch_cpu_init_dm, mark_bootstage, /* need timer, go after init dm */ ... #if defined(CONFIG_ARM) || defined(CONFIG_MIPS) || \ defined(CONFIG_BLACKFIN) || defined(CONFIG_NDS32) || \ defined(CONFIG_SPARC) timer_init, /* initialize timer */ #endif ....... To solve the issue for all the paltform, we can move timer_init() call just before mark_bootstage() in this array... It should be ok for ARMV7 but I don't sure for other platform impacted - the other ARM platform or ARMV7 wich don't use generic timer - MIPS BLACKFIN NDS32 or SPARC and I don't sure of impact for other function called (board_early_init_f for example....) => This patch solve issue only in timer armv7 get_boot_us() can be called everytime without div by 0 issue (gd->arch.timer_rate_hz is not used) END Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Signed-off-by: Patrick Delaunay <patrick.delaunay73@gmail.com>

2016-11-29ARM: mx6: ddr: use Kconfig for inclusion of DDR calibration routinesEric Nelson
The DDR calibration routines are gated by conditionals for the i.MX6DQ SOCs, but with the use of the sysinfo parameter, these are usable on at least i.MX6SDL and i.MX6SL variants with DDR3. Also, since only the Novena board currently uses the dynamic DDR calibration routines, these routines waste space on other boards using SPL. Add a KConfig entry to allow boards to selectively include the DDR calibration routines. Signed-off-by: Eric Nelson <eric@nelint.com>
2016-11-29mx6: ddr: add routine to return DDR calibration dataEric Nelson
Add routine mmdc_read_calibration() to return the output of DDR calibration. This can be used for debugging or to aid in construction of static memory configuration. This routine will be used in a subsequent patch set adding a virtual "mx6memcal" board, but could also be useful when gathering statistics during an initial production run. Signed-off-by: Eric Nelson <eric@nelint.com>
2016-11-29mx6: ddr: pass mx6_ddr_sysinfo to calibration routinesEric Nelson
The DDR calibration routines have scattered support for bus widths other than 64-bits: -- The mmdc_do_write_level_calibration() routine assumes the presence of PHY1, and -- The mmdc_do_dqs_calibration() routine tries to determine whether one or two DDR PHYs are active by reading MDCTL. Since a caller of these routines must have a valid struct mx6_ddr_sysinfo for use in calling mx6_dram_cfg(), and the bus width is available in the "dsize" field, use this structure to inform the calibration routines which PHYs are active. This allows the use of the DDR calibration routines on CPU variants like i.MX6SL that only have a single MMDC port.

2016-11-29armv7: psci: cpu_off: flush D-Cache before disable D-CachePeng Fan
Before disable cache, need to first flush cache. There maybe dirty data in D-Cache before disable D-Cache. After disable D-Cache, the first store instructions in psci_v7_flush_dcache_all will directly store registers {r4-r5, r7, r9-r11, lr} to memory. If there is dirty data before disable D-Cache, psci_v7_flush_dcache_all will flush data to memory, and may overwrite the memory that hold the registers {r4-r5, r7, r9-r11, lr}. So before disable cache, first flush D-Cache.
