Subject: lpc2000: fix LPC810 programming support
X-Git-Tag: v0.8.0-rc1~124
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=cb6836f9235cd8c57cd08c7cb4121d2328d50155;p=openocd

lpc2000: fix LPC810 programming support

IAP commands fail on programming LPC810 because it has only 1kByte of SRAM.
This patch is fixing cmd51_max_buffer suitable size for LPC810,LPC811 and
other LPC1000 series.
Tested on a LPC810,LPC812,LPC11u14,and LPC1114(DIP28).
