Unnecessary pull-up resisors on flash chip
At the bottom of sheet 13, there are some pull-up resistors on the W_n and Hold_n input pins of the flash memory. These (R136 and R175) are unnecessary and those pins can be tied to Vcc P3V3 directly.
Note that, if this (obsolete) flash chip is replaced, as per issue #1655, this work package can be closed.
