It would be really great to get a review from Peng here, as his commit 28fff3fa1c
("imx: imx8mp_evk: fix boot issue") changed exactly this option from 0x10000 to 0x8000.

I've tested my local build with your patch and it boots OK, hence I cannot seem to find a
reasoning why the early malloc area size has been halved with above commit.
