Date: Thu, 20 Aug 2015 17:45:41 +0530 From: Varadarajan Narayanan <varada@...eaurora.org> To: Russell King <linux@....linux.org.uk>, Kumar Gala <galak@...eaurora.org>, Andy Gross <agross@...eaurora.org>, David Brown <davidb@...eaurora.org>, Stephen Boyd <sboyd@...eaurora.org>, Varadarajan Narayanan <varada@...eaurora.org>, Lina Iyer <lina.iyer@...aro.org>, Georgi Djakov <gdjakov@...sol.com>, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, linux-arm-msm@...r.kernel.org, linux-soc@...r.kernel.org Subject: [PATCH] ARM: Set proper TEXT_OFFSET for IPQ806x RAM starts at 0x40000000 for IPQ. The lower 21MB of RAM is used for Shared Memory and the kernel can start from 0x41500000. However, this cannot be accomodated within the current AUTO_ZRELADDR framework. If textofs-y is set to 0x01508000, compilation breaks with arch/arm/kernel/head.S:181: Error: invalid constant (1508000) after fixup Hence, cannot use Linux's self extractor. Instead, create a compressed image that will be de-compressed from U-Boot.
