+"""
+Step 1: Check and update Vivado Flash device CSV to include w25q128bv.
+
+Checks whether 'w25q128bv-spi-x1_x2_x4' is present in Vivado's
+xicom_cfgmem_part_table.csv. If not, appends the correct row.
+
+Usage:
+    python check_flash_csv.py --vivado-dir "D:/Xilinx/Vivado/2018.1"
+
+Exit codes:
+    0 = device already present (no changes made)
+    2 = device was successfully added (Vivado restart required)
+    1 = error (CSV not found or write failure)
