deepikabhavnani did the hard work in tracking this issue down. Block
addresses are not cast to the correct type until after multiplying to
convert to byte addresses. This results in an overflow when the storage
is larger than 4 GB.
FATFilesystem declares sector count and size as uint32_t and block
device class arguments are addr and size which is uint64_t
While passing arguments to program/read/write API's of block device,
multiplication of uint32_t*uint32_t was not typecasted properly to
uint64_t which resulted in MSB truncation.
Eg. If block 0x800000 is accessed with block size 0x200, addr to be
passed (0x800000*0x200)0x100000000, but actual address passed was 0x0
which resulted in over-writting the root directory, and hence corrupted
filesystem
I added the function declarations of Ethernet functions that have a WEAK attribute. Although several Ethernet functions was called in rza1_emac.c, GR-LYCHEE don't have Ethernert feature. But there may be case that GR-LYCHEE uses LWIP feature.
In this case, since GR-LYCHEE will occur the build error, I addressed the error by defining the functions with a WEAK attribute. For reason of WEAK attribute, there is no influence in GR-PEACH and VK_RZ_A1H that have Ethernet feature.
I modified the debug message when using LWIP in RZ/A1 related mbed boards.
In eth_arch_enetif_init(), sys_thread_new() was called and task name is appeared as debug information, but task name for debug was a mistake.
For LWIP communication speedup in RZ_A1 related, I changed the below macro value and added the definition processing in RZ/A1 related header file(lwipopts_conf.h). For this reason, those macros are overrode by RZ/A1 related values, not default values.
In the below "features/FEATURE_LWIP" folders, same as Cortex-M targets, I changed the folder structure to combine files that can be shared as RZ/A1 related. And I renamed the folder name to "TARGET_RZ_A1XX" in order to make commonality explicit.
- "features/FEATURE_LWIP" folder

Call underlying HAL implementation to enter critical section/disable interrupts
before incrementing the global critical section counter.
Modify HAL implementations to track first entrances to the critical section and
only update the saved state on first enter.
