* env_sf: Fix recovery defaultMario Schuknecht2015-04-071-2/+4
| | | | | | | | | | | | | | | | | | | | | The u-boot environment is redundantly stored in a NOR flash on our boards. Redundant means that there are two places to store the environment. But only one of the two is active. I discovered that on one board the u-boot (env_sf) uses the environment from the second place and the Kernel (fw_printenv) uses the environment from the first place. To decide which is the active environment there is a byte inside the environment. 1 means active and 0 means obsolete. But on that board both environments had have a 1. This can happen if a power loss or reset occurs during writing the environment. In this situation the u-boot (env_sf) implementation uses the second environment as default. But the Kernel (fw_printenv) implementation uses the first environment as default. This commit corrects the default in the u-boot env_sf implementation when a problem was detected. Now the recovery default is the same like in all other environment implementations. E.g. fw_printenv and env_flash. This ensures that u-boot and Kernel use the same environment.

* arc: clean-up init procedureAlexey Brodkin2015-04-031-4/+4
| | | | | | | | | | | | | | | | Intention behind this work was elimination of as much assembly-written code as it is possible. In case of ARC we already have relocation fix-up implemented in C so why don't we use C for U-Boot copying, .bss zeroing etc. It turned out x86 uses pretty similar approach so we re-used parts of code in "board_f.c" initially implemented for x86. Now assembly usage during init is limited to stack- and frame-pointer setup before and after relocation. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Simon Glass <sjg@chromium.org>
* nand: yaffs: Remove the "nand write.yaffs" commandPeter Tyser2015-03-301-15/+0
| | | | | | | | | | | | | | | | This command is only enabled by one board, complicates the NAND code, and doesn't appear to have been functioning properly for several years. If there are no bad blocks in the NAND region being written nand_write_skip_bad() will take the shortcut of calling nand_write() which bypasses the special yaffs handling. This causes invalid YAFFS data to be written. See http://lists.denx.de/pipermail/u-boot/2011-September/102830.html for an example and a potential workaround. U-Boot still retains the ability to mount and access YAFFS partitions via CONFIG_YAFFS2. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* cmd_nand: Verify writes to NANDPeter Tyser2015-03-301-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously NAND writes were only verified when CONFIG_MTD_NAND_VERIFY_WRITE was defined. On boards without this define writes could fail silently. Boards with CONFIG_MTD_NAND_VERIFY_WRITE could prematurely report failures which ECC could correct. Add a verification step after all "nand write[.x]" commands to ensure the writes were successful. The verification uses ECC for for "normal" writes, but does not for raw and yaffs writes. Some test cases which inject fake bad bits on a 2K page flash are below. Test cases with CONFIG_MTD_NAND_VERIFY_WRITE defined: Example of an ECC write which previously failed when CONFIG_MTD_NAND_VERIFY_WRITE was defined, but now succeeds because ECC is used during verification: nand erase 0 0x10000 dhcp /somefile mw.b 0x10000 0xff 0x2000 mw.b 0x10020 0xfe 1 nand write.raw 0x10000 0x800 1 mw.b 0x1000020 0x01 1 nand write 0x1000000 0x800 0x1800 Test cases without CONFIG_MTD_NAND_VERIFY_WRITE defined: Example of an ECC write which previously silently failed: nand erase 0 0x10000 dhcp /somefile mw.b 0x10000 0xff 0x2000 mw.b 0x10020 0x00 1 nand write.raw 0x10000 0x800 1 mw.b 0x1000020 0xff 1 nand write 0x1000000 0x800 0x1800 Example of a raw write which previously failed silently due to stuck data bit, but now errors out: nand erase 0 0x10000 dhcp /somefile mw.b 0x10000 0xff 0x2000 mw.b 0x10020 0xfe 1 nand write.raw 0x10000 0x800 1 mw.b 0x1000020 0x01 1 nand write.raw 0x1000000 0x800 3 Example of a raw write which previously failed silently due to stuck OOB bit, but now errors out: nand erase 0 0x10000 dhcp /somefile mw.b 0x10000 0xff 0x2000 mw.b 0x10810 0xfe 1 nand write.raw 0x10000 0x800 1 mw.b 0x1000810 0x01 1 nand write.raw 0x1000000 0x800 3 Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Tested-by: Heiko Schocher <hs@denx.de> Acked-by: Heiko Schocher <hs@denx.de>

* common/board_f: move board_init_f_mem() from #else CONFIG_X86Alexey Brodkin2015-03-281-2/+4
| | | | | | | | | | | | | | | | | | | | Purpose of this change is to make it possible to re-use code currently used on X86 solely for other architectures. For example: * init_sequence_f_r * board_init_f_r Even though board_init_f_mem() has nothing to do with any particular architecture it won't work (at least in current implementation) for X86. This is because on X86 "gd" is an alias to function get_fs_gd_ptr(), thus we cannot assign anything to it. So this change separates selection of board_init_f_mem() from X86 while keeping it disabled for X86 still.

An example would be a Tegra124 system (where RAM starts at 2GB physical) that has more than 2GB of RAM. In this case, we can gd->ram_size to represent the actual RAM size, so that the actual RAM size is passed to the OS. This is useful if the OS implements LPAE, and can actually use the "extra" RAM. However, U-Boot does not implement LPAE and so must deal with 32-bit physical addresses. To this end, we enhance board_get_usable_ram_top() to detect the "over-sized" case, and limit the relocation addres so that it fits into 32-bits of physical address space.

This config is an expert option and is enabled by default. The all amount of memory reserved for the malloc, is by default set to zero in mem_malloc_init(). When the malloc reserved memory exceeds few MiB, then the boot process can slow down. So disabling this config, is an expert option to reduce the boot time, and can be disabled by Kconfig. Note: After disable this option, only calloc() will return the pointer to the zeroed memory area. Previously, without this option, the memory pointed to untouched malloc memory region, was filled with zeros. So it means, that code with malloc() calls should be reexamined.

Since some SPL features (such as MMC and environment) require a lot of stack, some boards set CONFIG_SPL_STACK to point into SDRAM. They then set up SDRAM very early, before board_init_f(), so that the larger stack can be used. This is an abuse of lowlevel_init(). That function should only be used for essential start-up code which cannot be delayed. An example of a valid use is when only part of the SPL code is visible/executable, and the SoC must be set up so that board_init_f() can be reached. It should not be used for SDRAM init, console init, etc. Add a CONFIG_SPL_STACK_R option, which allows the stack to be moved to a new address before board_init_r() is called in SPL. The expected SPL flow (for CONFIG_SPL_FRAMEWORK) is documented in the README.

* | cmd_i2c: Provide option for bulk 'i2c write' in one transactionLubomir Popov2015-02-191-9/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I2C chips do exist that require a write of some multi-byte data to occur in a single bus transaction (aka atomic transfer), otherwise either the write does not come into effect at all, or normal operation of internal circuitry cannot be guaranteed. The current implementation of the 'i2c write' command (transfer of multiple bytes from a memory buffer) in fact performs a separate transaction for each byte to be written and thus cannot support such types of I2C slave devices. This patch provides an alternative by allowing 'i2c write' to execute the write transfer of the given number of bytes in a single bus transaction if the '-s' option is specified as a final command argument. Else the current re-addressing method is used. Signed-off-by: Lubomir Popov <l-popov@ti.com> hs: adapt to CONFIG_DM_I2C

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you want to inspect the control device tree using the fdt command, the "fdt address -c" command previously unhelpfully printed the phys memory address of the device tree. That address could not then be used to set the fdt address for inspection. Changed the resulting print to one that can be copied directly to the 'fdt address <addr>' command.
