Johan Hedberg c1485fe2f8 boards: arduino_101: Set sensible default for SPI_0_CS_GPIO
The SPI_0_CS_GPIO and SPI_0_CS_GPIO_PIN values were defaulting to
something not very usable, because of which e.g. the file system
test app was having to explicitly set the right values in its sample
configuration. Having a proper defaults in the board defconfig means
this isn't needed anymore.

Title: Zephyr File System Demo

Description:

Demonstrates basic file and dir operations using the Zephyr file system.
--------------------------------------------------------------------------------

Building and Running Project:

The demo will run on Arduino 101 and will use the on-board SPI flash.

    make BOARD=arduino_101

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info

--------------------------------------------------------------------------------

Sample Output:

File System Demo!

Creating new file testfile.txt
Opened file testfile.txt
Data successfully written!
Data written:"hello world!"

Data successfully read!
Data read:"hello world!"

Data read matches data written!

Truncate tests:
Testing shrink to 0 size
Testing write after truncating
Data successfully written!
Data written:"hello world!"

Original size of file = 12
File size after shrinking by 5 bytes = 7
Check original contents after shrinking file
Data successfully read!
Data read:"hello w"

File size after expanding by 10 bytes = 17
Check original contents after expanding file
Data successfully read!
Data read:"hello w"

Testing for zeroes in expanded region
Closed file testfile.txt
File (testfile.txt) deleted successfully!
Created dir sub1!
Creating new file testfile.txt
Opened file testfile.txt
Creating new file sub1/testfile.txt
Opened file sub1/testfile.txt
Data successfully written!
Data written:"1"

Data successfully written!
Data written:"12"

Closed file testfile.txt
Closed file sub1/testfile.txt

Listing dir /:
[DIR ] SUB1
[FILE] TESTFILE.TXT (size = 1)

Listing dir sub1:
[FILE] TESTFILE.TXT (size = 2)

Removing files and sub directories in sub1
Removing sub1/TESTFILE.TXT
Removed dir sub1!

Optimal transfer block size   = 512
Allocation unit size          = 512
Volume size in f_frsize units = 152
