From mboxrd@z Thu Jan 1 00:00:00 1970 From: Pratyush Yadav Date: Wed, 5 May 2021 15:11:18 +0530 Subject: [PATCH v9 08/28] arm: mvebu: x530: Use tiny SPI NOR In-Reply-To: <20210505094138.30805-1-p.yadav@ti.com> References: <20210505094138.30805-1-p.yadav@ti.com> Message-ID: <20210505094138.30805-9-p.yadav@ti.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de The SPI NOR core will get Octal DTR in following commits. This has presented a significant challenge of keeping the SPL size in check on the x530 platform. On a previous iteration of the series, adding a set of compile-time switches got the build working. But rebasing on the latest master breaks the build again. We are fighting a losing battle here. Every addition to either the SPI NOR core in the future, or any other core part of U-Boot will potentially lead to the SPL size going beyond the limit and the build failing. To combat this we will have to keep adding more and more compile-time switches, increasing the complexity of the code in the process. This is not sustainable. So use tiny SPI NOR instead. It is designed with size-limited SPL binaries in mind, and will afford us more breathing room. To enable tiny SPI NOR, CONFIG_SPI_FLASH_BAR has to be disabled.
