Subject: [U-Boot] [PATCH v3 1/2] m68k: add malloc memory for early malloc
Date: Mon, 25 Apr 2016 16:28:33 +0200 [thread overview]
Message-ID: <571E2991.8000705@sysam.it> (raw)

Hi Simon,
noticed just after sending the patch an issue with my tests,
please freeze the patch, there are possible issues in it.
Will confirm this v3 in case after re-testing or will issue a v4.
thanks,
regards,
Angelo Dureghello
