Adds a dated review section recording today's actual schematic check
against every real ball assignment in this chapter: confirmed-correct
items, two real findings needing correction (boot-flash net-name
mismatch FGPA/FPGA typo + SCLK/CLK label mismatch that would leave the
flash electrically disconnected from the ECP5's config engine; SDRAM
CAS#/WE# appearing swapped vs. the verified F7/F9 assignment), and
open items not resolvable from the schematic image alone (regulator EN
pins, a stray +1V1 label near the VCCAUX ferrite, JTAG pull-up/down
array polarity).
Also reserves a "PCB module form factor" section (castellated-edge SMD
module, ~50x25mm) for the future physical layout.
Compiled clean (46 pages, 0 errors).
