When Linux kernel boots, it hangs at:

- The file content is "key=value" without any terminating byte (e.g. 0x0a or

fdt: add new fdt address parsing functions

fdtdec_get_addr_size() hard-codes the number of cells used to represent
an address or size in DT. This is incorrect in many cases depending on
the DT binding for a particular node or property (e.g. it is incorrect
for the "reg" property). In most cases, DT parsing code must use the
properties #address-cells and #size-cells to parse addres properties.

This change splits up the implementation of fdtdec_get_addr_size() so
that the core logic can be used for both hard-coded and non-hard-coded
cases. Various wrapper functions are implemented that support cases
where hard-coded cell counts should or should not be used, and where
the client does and doesn't know the parent node ID that contains the
properties #address-cells and #size-cells.

dev_get_addr() is updated to use the new functions.

Core functionality in fdtdec_get_addr_size_fixed() is widely tested via
fdtdec_get_addr_size(). I tested fdtdec_get_addr_size_auto_noparent() and
dev_get_addr() by manually modifying the Tegra I2C driver to invoke them.

Much of the core implementation of fdtdec_get_addr_size_fixed(),
fdtdec_get_addr_size_auto_parent(), and
fdtdec_get_addr_size_auto_noparent() comes from Thierry Reding's
previous commit "fdt: Fix fdtdec_get_addr_size() for 64-bit".

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

4. mx6ul_9x9_evk use lpddr2 with size 256MB, so add related SPL DRAM
   configurations.
5. Enable CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG and setting dtb file
   according to board_rev and board_name.
6. Add TARGET_MX6UL_9X9_EVK Kconfig entry

usb: ci_udc: fix emissions of ZLPs

Commit 6a132416359e "ci_udc: Update the ci_udc driver to support bulk
transfers" caused the value of "len" to change without updating subsquent
users of that variable in ci_ep_submit_next_request(). This caused the
code that detects when to emit ZLPs (Zero Length Packets) never to
trigger, which in turn caused host timeouts when a ZLP was required,
which in turn broke tests/dfu/, even despite the assertion in that
commit's description that "These changes are tested for both the DFU and
lthor."

Fix this by modifying the added dtd iteration code not to modify "len",
but rather to keep state in a separate variable. Rename the variables
while we're at it so they describe their purpose better.

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
