+# parameters:
+# - chip_name - name of the chip, e.g. lpc2103
+# - cputapids - TAP IDs of the core, should be quoted if more than one, e.g. 0x4f1f0f0f or "0x3f0f0f0f 0x4f1f0f0f"
+# - flash_size - size of on-chip flash (available for code, not including the bootloader) in bytes, e.g. 0x8000
+# - flash_variant - "type" of LPC2xxx device, lpc2000_v1 (LPC22xx and older LPC21xx) or lpc2000_v2 (LPC213x, LPC214x, LPC210[123], LPC23xx and LPC24xx)
+# - workarea_size - size of work-area in RAM for flashing procedures, must not exceed the size of RAM available at 0x40000000, e.g. 0x2000
+# - core_freq_khz - frequency of core in kHz during flashing, usually equal to connected crystal or internal oscillator, e.g. 12000
+# - adapter_freq_khz - frequency of debug adapter in kHz, should be 8x slower than core_freq_khz, e.g. 1000
