[PATCH v5 07/20] net-lwip: build lwIP

Jerome Forissier
2024-07-25T12:59:14Z

Build the lwIP library when NET_LWIP is enabled. The following files
are adaptation layers written specially for U-Boot:

lib/lwip/u-boot/arch/cc.h
lib/lwip/u-boot/arch/sys_arch.h (empty)
lib/lwip/u-boot/limits.h (empty)
lib/lwip/u-boot/lwipopts.h

They were initially contributed by Maxim in a previous RFC patch series.
