[Buildroot] [PATCH 1/1] configs: new defconfig for TI am335x-evm_sgx-qt5

[Lothar Felten]

Add a target configuration for the ti am335x-evm that supports the SGX530
graphics acceleration and builds the qt5 demos with the eglfs backend.
The imagination technologies demos and fbv are also included.
The linux kernel is based on the omap2plus defconfig, a config fragment
adds the required settings for SGX accelerator support.

This looks good, but I have the same comments as the
am335x_evm_defconfig: i.e does it really supports multiple boards.

Also, I believe it would be useful to reference this defconfig in the
readme.txt file added in the previous patch.

Both patches should be sent in a series, since this patch depends on
the first one.

Great idea to use a config fragment here.

Please this am335x_evm_sqx_qt5_deconfig

Please use the "headers from the kernel source" option.

Thanks!
