* ARM: start: Fix code reordering problemSascha Hauer2015-07-021-0/+2
| | | | | | | | | | | This adds a barrier after setup_c(). This is necessary because otherwise some global variable assignments may be reordered by the compiler to be executed before setup_c which cannot work. This was observed when doing other unrelated changes to the start function, it seems in current mainline state the compiler does not actually reorder the code.

* mx53-qsb: Fix boot hang during reboot stress testFabio Estevam2015-07-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the DDR init sequence the same way as done by aee0013e53b339a5 from U-boot in order to prevent the boot hang under reboot stress test. Quoting this commit log: "Currently by running the following test: => setenv bootcmd reset => save => reset , we observe a hang after approximately 20-30 minutes of stress reboot test. Investigation of this issue revealed that when a single DDR chip select is used, the hang does not happen. It only happens when the two chip selects are active. MX53 reference manual states at "28.6.2 Memory ZQ calibration sequence": "The controller must keep the memory lines quiet (except for CK) for the ZQ calibration time as defined in the Jedec (512 cycles for ZQCL after reset, 256 for other ZQCL and 64 for ZQCS)." According to the SDE_0 and SDE_1 bit descriptions from register ESDCTL_ESDCTL: "Writing 1 to SDE0 or SDE1 will initiate power up delays as JEDEC defines. Power up delays are a function of the configured memory type (DDR2/DDR3/LPDDR2)" So make sure to activate one chip select at time (CS0 first and then CS1 later), so that the required JEDEC delay is respected for each chip select. With this change applied the board has gone through three days of reboot stress test without any hang."

* mtd: m25p80: Fix Kconfig dependenciesSascha Hauer2015-06-291-1/+2
| | | | | | | | | | The m25p80 driver now depends on MTD_SPI_NOR which is disabled in all defconfigs, so this effectively disables the m25p80 driver in all defconfigs. Fix this by selecting MTD_SPI_NOR which is library code without further dependencies. Also let m25p80 depend on SPI because it needs the SPI code and won't link without it.

* PCI: remove bogus host bridge setup skippingLucas Stach2015-06-251-5/+0
| | | | | | | | | | Apparently this was here to fix issues with some QEMU version, but hasn't worked in the intended way for a long time. The probe code should be mature enough by now, so this workaround isn't needed anymore. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* login: fix broken login commandHubert Feurstein2015-06-181-1/+1
| | | | | | | | | | It was possible to login with ctrl-c or an empty password. This bug was introduced by the recent digest changes in common/password.c (e49a47fb). The function check_passwd returns now also negative error codes which were not correctly handled in do_login.

* scripts/omap_signGP: Fix image size in GP headerWadim Egorov2015-06-171-0/+7
| | | | | | | | | | | | The size field in the GP header has to include its own size. This can be easily misread in the TRM. Sometimes, when the gp_header size is not included, the ROM code will not copy the complete MLO into the SRAM. This happens when the MLO file size is 98823 bytes (and the value of GP header size field is 98303 bytes).

* clk: of: fix clk_of_table generationSascha Hauer2015-06-112-2/+3
| | | | | | | | | | | | | | We used to collect all sections beginning with __clk_of_table_ in a single section in the linker using KEEP(*(.__clk_of_table_*)). That the sentinel entry ended up as the last entry was pure luck, but not always the case. Instead of putting all entries in different sections we now put all entries in the same section. Only the sentinel entry gets its own section and is collected by the linker separately.
