imx: mx6ul: support mx6ul 9x9 evk board
This patch is to support mx6ul_9x9_evk board based on mx6ul_14x14_evk,
the difference between mx6ul 9x9 evk and mx6ul 14x14 evk are:
1. mx6ul 9x9 evk use pfuze3000, while mx6ul 14x14 evk use DCDC.
2. mx6ul 9x9 evk supports 256MB LPDDR2, while mx6ul 14x14 evk
supports 512MB DDR3
3. mx6ul_9x9_evk use 9x9 package, while mx6ul_14x14_evk use 14x14 package.
This patch add the following:
1. Discard PHYS_SDRAM_SIZE from header file, use imx_ddr_size()
2. Introduce a macro is_mx6ul_9x9_evk using
CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) to avoid "#ifdef xxx" in non-SPL
part. To SPL part, CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) can not work,
so still use "#ifdef CONFIG_TARGET_MX6UL_9X9_EVK" to differentiate with
mx6ul_14x14_evk. And we have no way to dymaically checking this chip
is 9x9 or 14x14.
3. mx6ul_9x9_evk use pfuze3000, so enabled POWER related configurations.
POWER related configurations also effect for mx6ul_14x14_evk. But
power_init_board implementation using 'if (is_mx6ul_9x9_evk())' to
do initialization for mx6ul_9x9_evk, and do nothing for mx6ul_14x14_evk.

configurations.
5. Enable CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG and setting dtb file
according to board_rev and board_name.

The current simplify lpc32xx gpio driver implementation assume a

1) When requesting GPI_xx and GPO_xx on port 3 (xx is the same number)
the second call to "gpio_request" will return -EBUSY.
2) The status of GPO_xx pin report the status of the
corresponding GPI_xx pin when using the "gpio status" command.
3) The gpio driver may setup the direction register for the wrong
gpio when calling "gpio_direction_input" (GPI_xx) or

direction is require to use the "gpio status" command.
The following change were done in the driver:
1) port3 GPI are cache in a separate 32 bits in the array.
2) port3 direction register written only for GPIO pins.
3) port3 GPO & GPIO (as output) are read using "p3_outp_state".

dfu: mmc: buffer file reads too
When writing to files in a filesystem on MMC, dfu_mmc.c buffers up the
entire file content until the end of the transaction, at which point the
file is written in one go. This allows writing files larger than the USB
transfer size (CONFIG_SYS_DFU_DATA_BUF_SIZE); the maximum written file
size is CONFIG_SYS_DFU_MAX_FILE_SIZE (the size of the temporary buffer).
The current file reading code does not do any buffering, and so limits
the maximum read file size to the USB transfer size. Enhance the code to
do the same kind of buffering as the write path, so the same file size
limits apply.
Remove the size checking code from dfu_read() since all read paths now
support larger files than the USB transfer buffer.

dfu: don't keep freeing/reallocating
DFU currently allocates buffer memory at the start of each data transfer
operation and frees it at the end. Especially since memalign() is used to
allocate the buffer, and various other allocations happen during the
transfer, this can expose the code to heap fragmentation, which prevents
the allocation from succeeding on subsequent transfers.
Fix the code to allocate the buffer once when DFU mode is initialized,
and free the buffer once when DFU mode is exited, to reduce the exposure
to heap fragmentation.
The failure mode is:
// Internally to memalign(), this allocates a lot more than s to guarantee
// that alignment can occur, then returns chunks of memory at the start/
// end of the allocated buffer to the heap.
p = memalign(a, s);
// Various other malloc()s occur here, some of which allocate the RAM
// immediately before/after "p".
//
// DFU transfer is complete, so buffer is released.
free(p);
// By chance, no other malloc()/free() here, in DFU at least.
//
// A new DFU transfer starts, so the buffer is allocated again.
// In theory this should succeed since we just free()d a buffer of the
// same size. However, this fails because memalign() internally attempts
// to allocate much more than "s", yet free(p) above only free()d a
// little more than "s".

usb: gadget: don't leak configs when unbinding
By the time g_dnl_unbind() is run, cdev->config has been set to NULL,
so the free() there does nothing, and the config struct is leaked.
Equally, struct usb_gadget contains a linked list of config structs, so
the code should iterate over them all and free each one, rather than
freeing one particular config struct.
composite_unbind() already iterates over the list of config structs, and
unlinks each from the linked list. Fix this loop to free() each struct as
it's unlinked and otherwise forgotten.
FIX: fat: Provide correct return code from disk_{read|write} to upper layers
It is very common that FAT code is using following pattern:
if (disk_{read|write}() < 0)
return -1;
Up till now the above code was dead, since disk_{read|write) could only
return value >= 0.
As a result some errors from medium layer (i.e. eMMC/SD) were not caught.
The above behavior was caused by block_{read|write|erase} declared at
struct block_dev_desc (@part.h). It returns unsigned long, where 0
indicates error and > 0 indicates that medium operation was correct.
This patch as error regards 0 returned from block_{read|write|erase}
when nr_blocks is grater than zero. Read/Write operation with nr_blocks=0
should return 0 and hence is not considered as an error.
