In order to set own exception handlers, a table with the exception vectors must be built in DRAM and the CPU EBase register must be set to the base address of this table. Reserve the space above the stack and use gd->irq_sp as storage for the exception base address. Signed-off-by: NDaniel Schwierzeck <daniel.schwierzeck@gmail.com>

This adds a new Kconfig option CONFIG_MIPS_INIT_STACK_IN_SRAM which a SoC can select if it supports some kind of SRAM. Together with CONFIG_SYS_INIT_SP_ADDR the initial stack and global data can be set up in that SRAM. This can be used to provide a C environment also for lowlevel_init().

Clear cp0 status while preserving implementation specific bits. Set bits BEV and ERL as the arch specification requires after a reset or soft-reset exception. Extend and fix initialization of watch registers. Check if additional watch register sets are implemented and initialize them too. Initialize cp0 count as early as possible to get the most accurate boot timing. Signed-off-by: NDaniel Schwierzeck <daniel.schwierzeck@gmail.com>

When booting from ROM, early exceptions can't be handled properly. Instead of busy-looping give the developer the possibilty to examine the situation. Invoke an UHI exception operation which can be read as unhandled exception by a hardware debugger if one is attached. If the debugger doesn't support UHI, the exception is read as unexpected breakpoint. Signed-off-by: NDaniel Schwierzeck <daniel.schwierzeck@gmail.com>

This adds a compile time option to include code for static exception vectors. Static exception vectors are only needed, when the U-Boot entry point is equal to the CPU reset exception vector address. For instance this is the case when U-Boot is used as ROM in Qemu or booted from parallel NOR flash. When U-Boot is booted from RAM (e.g. loaded there by SPL), the exception vectors need to be setup dynamically, which is done in follow-up commits.

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.

Juno uses a 1:1 mapping between CPU and PCI addresses for IO.

When using OF_CONTROL, the disabled value of the mini UART platdata gets reset after board_early_init_f. So move detection and disabling to board_init and remove board_early_init_f.

fill_dir_slot use get_contents_vfatname_block as a temporary buffer for constructing a list of dir_slot entries. To save the memory and providing correct type of memory for above usage, a local buffer with accurate size declaration is introduced. The local array size 640 is used because for long file name entry, each entry use 32 bytes, one entry can store up to 13 characters. The maximum number of entry possible is 20.

This fixes the loop delay when using a hw watchdog. In case a watchdog is used that accesses CPU registers, the defined delay of 20us in a tight loop will cause a huge delay in the actual timeout seen. This is caused by the fact that udelay will inheritantly call WATCHDOG_RESET. Together with the omap wdt implementation, the seen timeout increases up to around 30s. This makes the loop very slow and causes long delays when using the modem. Instead, implement the 2 sec loop by using the timer interface to know when to break out of the timeout loop. Watchdog kicking is taken care of by getc(). Signed-off-by: NTomas Melin <tomas.melin@vaisala.com>

Commit d97dc8a0 separated the non-command code into its own file which caused variable sata_curr_device can not be set to a correct value. Before commit d97dc8a0, variable sata_curr_device can be set correctly in sata_initialize(). After commit d97dc8a0, sata_initialize() is moved out to its own file. Accordingly, variable sata_curr_device is removed from sata_initialize() too. This caused sata_curr_device never gets a chance to be set properly which prevent other commands from being executed.

commit 183923d3 enforces that the environment must start at an erase block boundary. For block devices the sample fw_env.config does not mandate a erase block size for block devices. A missing setting defaults to the full env size. Depending on the environment location the alignment check now errors out for perfectly legal settings. Fix this by defaulting to the standard blocksize of 0x200 for environments stored in a block device. That keeps the fw_env.config files for block devices working even with that new check.

Commit c68c62 ("i2c: mvtwsi: Make delay times frequency-dependent") extensively used the ndelay function with a calculated parameter which is dependant on the configured frequency of the I2C bus. If standard speed is employed, the parameter is usually 10000 (10000ns period length for 100kHz frequency). But, since the arm architecture does not implement a proper version of ndelay, the fallback default from include/linux/compat.h is used, which defines every ndelay as udelay(1). This causes problems for slower speeds on arm, since the delay time is now 9us too short for the desired frequency, which leads to random failures of the I2C interface. To remedy this, we implement a proper, parameter-aware ndelay fallback for architectures that don't implement a real ndelay function.
