2016-06-04nand: Embed mtd_info in struct nand_chipScott Wood
nand_info[] is now an array of pointers, with the actual mtd_info instance embedded in struct nand_chip. This is in preparation for syncing the NAND code with Linux 4.6, which makes the same change to struct nand_chip. It's in a separate commit due to the large amount of changes required to accommodate the change to nand_info[]. Signed-off-by: Scott Wood <oss@buserror.net>

2016-05-20drivers: mtd: add Microchip PIC32 internal non-CFI flash driver.Purna Chandra Mandal
PIC32 internal flash devices are parallel NOR flash divided into number of banks to allow erase-programming in one while fetch and execution continues on other. As the flash banks are memory mapped stored code can be executed directly from flash (XIP), also there is additional hardware logic to prefetch and cache contents to improve execution performance. These flash can also be used to store user data (like environment). Flash erase and programming are handled by on-chip NVM controller. Driver implemented driver model but MTD is not really support.

The S25FS-S family physical sectors may be configured as a hybrid combination of eight 4-kB parameter sectors at the top or bottom of the address space with all but one of the remaining sectors being uniform size. The default status of the flash is in this hybrid architecture. The parameter sectors and the uniform sectors have different erase commands.

2016-04-25sf: fix timebase data type in _wait_ready()Stephen Warren
get_timer() returns an unsigned 64-bit value, but is currently assigned to a signed 32-bit variable. Due to sign extension and data truncation, this causes the timeout loop in spi_flash_cmd_wait_ready() to immediately (and incorrectly) fire for about 50% of all time values, based on whether bit 31 is set. In sandbox at least, this causes the test to pass or fail based on system uptime, as opposed to time since the U-Boot binary was started.

2016-04-22mtd, ubi: set free_count to zero before walking through erase listHeiko Schocher
Set free_count to zero before walking through ai->erase list in wl_init(). As U-Boot has no workqueue/threads, it immediately calls erase_worker(), which increase for each erased block free_count. Without this patch, free_count gets after this initialized to zero in wl_init(), so the free_count variable always has the maybe wrong value 0. Detected this behaviour on the dxr2 board, where the UBI fastmap gets not written when attaching/dettaching on an empty NAND. It drops instead the error message: could not find any anchor PEB With this patch, fastmap gets written on dettach.

2016-03-12sf: Correct data types in stm_is_locked_sr()Marek Vasut
The stm_is_locked_sr() function is picked from Linux kernel. For reason unknown, the 64bit data types used by the function and present in Linux were replaced with 32bit unsigned ones, which causes trouble. The testcase performed was done using ST M25P80 chip. The command used was: => sf protect unlock 0 0x10000 The call chain starts in stm_unlock(), which calls stm_is_locked_sr() with negative ofs argument. This works fine in Linux, where the "ofs" is loff_t, which is signed long long, while this fails in U-Boot, where "ofs" is u32 (unsigned int). Because of this signedness problem, the expression past the return statement to be incorrectly evaluated to 1, which in turn propagates back to stm_unlock() and results in -EINVAL. The correction is very simple, just use the correctly sized data types with correct signedness in the function to make it work as intended.
