Exynos has buggy firmware that puts bad data into the memory node. Commit 1c2f87c2 (ARM: Get rid of meminfo) exposed the bug by dropping the artificial upper bound on the number of memory banks that can be added. Exynos fails to boot after that commit. This branch fixes it by splitting the early DT parse function and inserting a fixup hook. Exynos uses the hook to correct the DT before parsing memory regions. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJT2HI1AAoJEMWQL496c2LNvfAP/ifY6foyrO2MHGxlGdghL3Xe fHY+MxoywBqWwLuXjfSh0rIt/5KE80JvtTjnssSOHOZokOPa/O3N39SrQPaLRqW8 1XC5A/Qocokeii69iXgXn0aQChBhyrRW708q9iU43ucKwcmWNvrzgdq838XdVB3q BGHeV9ADn57PHAitsOrDCJei//jgs94NXDKPmCwrTn62aiedeiiMAWYUfsPXFtsn gloL8wT8gcD8ojaSvKWpGJtUbkFBNe1DVQgsmIfG0hNUuolpsbNZo688OoWJUCaj 0qQ2LqHD2djDMqxxj0xFxOx7GoQPZjAG9NlLkca3QG5dc1S+Bf//g11uxRAHQ2qD 3l24i825fp4kGL1NUfR+OK4PIqGwBbEnXoIgrWnVjQxw/adMlH3iWFfuZqe/fBIq 4CTe9buc+JGCdJUAp+DS3YRYtFPdlovgaJjCAAwKWEd4GpjLEKrGGL/dAkhyRP/j 77byHy8XgSB5moh7qiR0u1M3lyRmU54f5EdDimPGaMUJ2PSzSxuYZk41hRRrstVn JCzDmblvTF4wai3t4Z+laUP0dAym/gwX/87UiRsO+hyXKGiVCq9AmDkueL2xLUuV c8rqjXLcVZ5qicLP2uCtWpz96WVzTCa3CzcMufT7t6cErMLueSSARrxq2RrETsFo SpeBf3cc90Edv8LP7V9W =lmyQ -----END PGP SIGNATURE----- Merge tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux Pull Exynos platform DT fix from Grant Likely: "Device tree Exynos bug fix for v3.16-rc7 This bug fix has been brewing for a while. I hate sending it to you so late, but I only got confirmation that it solves the problem this past weekend. The diff looks big for a bug fix, but the majority of it is only executed in the Exynos quirk case. Unfortunately it required splitting early_init_dt_scan() in two and adding quirk handling in the middle of it on ARM. Exynos has buggy firmware that puts bad data into the memory node.
