Ilias Apalodimas <ilias.apalodimas@linaro.org> says:

Hi all,

This is a respin of [1] adding https support to wget. In short

patch#1 enables the crypto algorithms we need in mbedTLS
patches#2, #3 enable anf fix the lwIP part we need
patch#4 is adding https:// parsing support in our wget
patch#5 is making https:// the default for QEMU lwip defconfig so
people can easily test
and finaly patch#6 updates our documentation
