* arm: armv7: add compile option -mno-unaligned-access if availableTetsuyuki Kobayashi2012-07-20-0/+2
| | | | | | | | | | Recent compiler generates unaligned memory access in armv7 default. But current U-Boot does not allow unaligned memory access, so it causes data abort exception. This patch add compile option "-mno-unaligned-access" if it is available. Signed-off-by: Tetsuyuki Kobayashi <koba@kmckk.co.jp> Tested-by: Gary Thomas <gary@mlbassoc.com>
* arm: Fix to mistake clean the memory spaceZhong Hongbo2012-07-20-3/+5
| | | | | | | | | | | In currently, when __bss_start is equal to __bss_end__, The bss loop will clear all the things in memory space. But just only when __bss_end__ greater than __bss_start__, we do the clear bss section operation.

| * tegra: add enterrcm commandStephen Warren2012-07-09-0/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra's boot ROM supports a mode whereby code may be downloaded and flash programmed over a USB connection. On dev boards, this is typically entered by holding down a "force recovery" button and resetting the CPU. However, not all boards have such a button (one example is the Compulab Trimslice), so a method to enter RCM from software is useful. This change implements the command "enterrcm" to do this, and enables it for all Tegra boards by default. Even on boards other than Trimslice, controlling this over a UART may be useful, e.g. to allow simple remote control without the need for mechanical button actuators, or hooking up relays/... to the button.

* OMAP4+: Force DDR in self-refresh after warm resetLokesh Vutla2012-07-07-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Errata ID:i727 Description: The refresh rate is programmed in the EMIF_SDRAM_REF_CTRL[15:0] REG_REFRESH_RATE parameter taking into account frequency of the device. When a warm reset is applied on the system, the OMAP processor restarts with another OPP and so frequency is not the same. Due to this frequency change, the refresh rate will be too low and could result in an unexpected behavior on the memory side. Workaround: The workaround is to force self-refresh when coming back from the warm reset with the following sequence: • Set EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE to 0x2 • Set EMIF_PWR_MGMT_CTRL[7:4] REG_SR_TIM to 0x0 • Do a dummy read (loads automatically new value of sr_tim) This will reduce the risk of memory content corruption, but memory content can't be guaranteed after a warm reset. This errata is impacted on OMAP4430: 1.0, 2.0, 2.1, 2.2, 2.3 OMAP4460: 1.0, 1.1 OMAP4470: 1.0 OMAP5430: 1.0 Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Signed-off-by: R Sricharan <r.sricharan@ti.com> Signed-off-by: Senthilvadivu Guruswamy <svadivu@ti.com>

* i.MX6 USDHC: Use the ESDHC clockMichael Langer2012-07-07-0/+4
| | | | | | | | | | | | | | | The commit "i.mx: fsl_esdhc: add the i.mx6q support" (4692708d) introduces support for the i.MX6Q MMC host controller USDHC. MXC_IPG_PERCLK sets the clock to 66MHz. This seems to be the default clock of the ESDHC IP found in < i.MX6 silicon. However, the default clock for the USDHC IP found in i.MX6 is 200MHz (MXC_ESDHC_CLK). This difference will cause a 3 times higher clock on SD_CLK than expected (see fsl_esdh.c -> set_sysctl()).

* ARM: OMAP5: dmm: Create a tiler trap section.SRICHARAN R2012-07-07-3/+3
| | | | | | | | | | | | | | | | | The unmapped entries in tiler space are set with values 0xFF. So creating a DMM section of size 16MB at 0xFF000000 with ADDRSPACE set to 0x2. This way all the unmapped entry accesses to tiler will be trapped by the EMIF and a error response is sent to the L3 interconnect. L3 errors are inturn reported to MPU. Note that here the tiler trap section is overlapping with the actual ddr physical space and we lose 16MB out of the total 2GB. Signed-off-by: R Sricharan <r.sricharan@ti.com>

The recent change to use -march=armv7-a for armv7 caused a regression on tegra because tegra starts boot on a arm7tdmi processor before transferring control to the cortex-a9. While still executing on the arm7tdmi there are calls to getenv_ulong() and memset() that cause an illegal instruction exception if compiled for armv7.

* arm, omap3: fix warm reset serial output on OMAP36xx/AM/DM37xxMatt Porter2012-05-15-0/+16
| | | | | | | | | | | | | | | | In warm reset conditions on OMAP36xx/AM/DM37xx the rom code incorrectly sets the DPLL4 clock input divider to /6.5 which is an invalid value unless the input clock is 13MHz. When a JTAG emulator is attached, a warm reset is necessary after the emulator gains control of the process. This results in a loss of serial output due to the invalid DPLL4 settings. This patch fixes the issue by resetting the DPLL4 clock input divider to /1 when the input clock is not 13MHz. AM/DM37x TRM section 3.5.3.3.3.2.1 specifies that the /6.5 setting is only used when the input clock is 13MHz. Signed-off-by: Matt Porter <mporter@ti.com>
